Golf Smarter number three hundred and fifty 2 00:00:05,040 --> 00:00:07,839 published on September twenty five, twenty twelve. 3 00:00:07,960 --> 00:00:13,039 Speaker 2: Welcome to golf Smarter Mulligans, your second chance to gain 4 00:00:13,080 --> 00:00:16,679 insight and advice from the best instructors featured on the 5 00:00:16,679 --> 00:00:22,679 Golf Smarter podcast. Great Golf Instruction Never gets old. Our 6 00:00:22,800 --> 00:00:27,600 interview library features hundreds of hours of game improvement conversations 7 00:00:27,719 --> 00:00:31,239 like this that are no longer available in any podcast app. 8 00:00:31,320 --> 00:00:34,000 Speaker 3: So we have a simple case, for example, a ten 9 00:00:34,039 --> 00:00:37,200 foot putt across flat green on a filt that you 10 00:00:37,320 --> 00:00:40,359 run into all the time, plus the break. How much 11 00:00:40,399 --> 00:00:42,719 does a break? So I've designed two futt putts to 12 00:00:42,759 --> 00:00:45,960 tell you all about it. You'll find a two percent slope. 13 00:00:46,079 --> 00:00:48,719 We've already described how you though it's two percent, walk 14 00:00:48,759 --> 00:00:51,560 straight down till one hundred inches away you can go, 15 00:00:51,600 --> 00:00:53,439 and then you stop, and you compare where your foot 16 00:00:53,520 --> 00:00:55,600 is to where the hole is, and what's the elevation 17 00:00:55,759 --> 00:00:58,119 drop from the hull to your foot. You imagine a 18 00:00:58,119 --> 00:01:01,000 stream coming out of the whole dead level and how 19 00:01:01,079 --> 00:01:02,880 it is as far as your foot, and hide of 20 00:01:02,920 --> 00:01:05,120 the string above your foot tells you how many inches 21 00:01:05,200 --> 00:01:08,400 it is to the surface. That's what percent. The slope is. 22 00:01:08,560 --> 00:01:10,719 If the string hits your foot at two inches off 23 00:01:10,719 --> 00:01:14,400 the ground, it's slope because you've went one hundred inches downhill. 24 00:01:14,719 --> 00:01:17,879 Two percent is to over one hundred it's a drop 25 00:01:18,000 --> 00:01:20,640 or rise of two inches, a very run of one 26 00:01:20,680 --> 00:01:24,359 hundred inches. That's the percent. It's also called the grade. 27 00:01:24,599 --> 00:01:26,959 If the string inch your foot at three inches off 28 00:01:27,000 --> 00:01:29,560 the ground, and that's a three percent slope. It's through 29 00:01:29,680 --> 00:01:31,480 the level of string from the ult your foot hits 30 00:01:31,480 --> 00:01:33,879 you in the ankle. That's a four percent slope. 31 00:01:37,959 --> 00:01:41,599 Speaker 1: A graduate level education on reading the greens with Jeff Manga. 32 00:01:41,799 --> 00:01:47,040 Speaker 2: This is Golf Smarter, sharing tips and insights from golfers 33 00:01:47,079 --> 00:01:50,560 and golf professionals to help lower your score. It's worked 34 00:01:50,599 --> 00:01:52,319 for your host, Fred Green. 35 00:01:52,760 --> 00:01:54,719 Speaker 1: Welcome back to Golf Smarter for remembers only. 36 00:01:54,879 --> 00:01:57,760 Speaker 3: Jeff, all right, go, I'm a jacket on. 37 00:01:58,719 --> 00:02:01,719 Speaker 1: We're back the coffee still at McDonald's. 38 00:02:02,439 --> 00:02:04,200 Speaker 3: I have a member's only jacket. 39 00:02:05,840 --> 00:02:07,799 Speaker 1: And you've had it since nineteen seventy seven. 40 00:02:08,280 --> 00:02:09,439 Speaker 3: Yeah, I got it from the thristle. 41 00:02:11,599 --> 00:02:14,080 Speaker 1: Well, this is a member's only episode and everyone's got 42 00:02:14,120 --> 00:02:14,840 their jackets. 43 00:02:17,199 --> 00:02:18,639 Speaker 3: Welcome fellow jacket word. 44 00:02:18,840 --> 00:02:21,240 Speaker 1: Yeah, you know for those of you who do remember 45 00:02:21,319 --> 00:02:25,400 members only jackets, I'm sorry, So let's talk about putting 46 00:02:25,439 --> 00:02:27,919 some more. Explain to me what a stimp meter is 47 00:02:28,000 --> 00:02:31,280 and what stimp means, and why we use that word, 48 00:02:31,520 --> 00:02:34,680 and is is it relevant to us as average golfers. 49 00:02:36,759 --> 00:02:44,159 Speaker 3: Well, let me just describe to you green speed and 50 00:02:44,400 --> 00:02:48,800 the role of stimp meter in knowing and using and 51 00:02:48,840 --> 00:02:54,879 appreciating green speed. Okay, Green speed is the friction in 52 00:02:54,919 --> 00:02:59,639 the grass that opposes the rolling of the ball. If 53 00:02:59,680 --> 00:03:01,960 you're an outer space and you hit a golf ball, 54 00:03:02,199 --> 00:03:04,639 there wouldn't be any friction and it would just go 55 00:03:04,759 --> 00:03:07,319 forever until it was captured by Jupiter or some of 56 00:03:07,360 --> 00:03:14,719 the planet. If you hit a ball on marble, it 57 00:03:14,759 --> 00:03:17,759 has very little friction and it will go for a 58 00:03:17,800 --> 00:03:23,080 long way. If you hit a ball across grass, the 59 00:03:23,159 --> 00:03:26,439 bottom of the grass is in contact with a certain 60 00:03:26,520 --> 00:03:30,680 area of the green grass, the same way the tread 61 00:03:30,759 --> 00:03:34,120 tires in contact with the road in a certain area. 62 00:03:35,319 --> 00:03:40,599 And that area there is basic electrostatic connection between the 63 00:03:40,639 --> 00:03:44,159 grass and the ball that opposes the directionality of the 64 00:03:44,199 --> 00:03:48,840 ball and slows it down and brings it to a stop. 65 00:03:50,599 --> 00:03:54,759 And some greens have less friction than others because they 66 00:03:54,759 --> 00:04:00,159 have tight, short packed grass that makes it more in 67 00:04:00,199 --> 00:04:03,759 the direction of marble. And some greens have more friction 68 00:04:03,960 --> 00:04:11,039 because they have shaggy, buoyant, bulbous, fast and bubbles grass 69 00:04:11,039 --> 00:04:15,039 blades with a lot of water inside them like water beds. 70 00:04:16,279 --> 00:04:20,279 Grass blades are like water beds, and so the more 71 00:04:21,360 --> 00:04:23,879 water there is in the grass blades and the shagger 72 00:04:23,879 --> 00:04:26,439 of the grass, the taller the grass, the less packed 73 00:04:26,519 --> 00:04:29,639 it is that will have a lot of friction. So 74 00:04:29,680 --> 00:04:33,519 there's a range of green speeds, and modern golf course 75 00:04:33,720 --> 00:04:39,639 architects and maintenance technology has tried to bring green speeds 76 00:04:39,759 --> 00:04:43,720 up to the limit of what keeps the grass healthy 77 00:04:44,319 --> 00:04:50,160 and keeps it fast and uniform and true. Today greens 78 00:04:50,199 --> 00:04:56,079 can easily be maintained at around nine feet on the stimpmeter, 79 00:04:57,160 --> 00:05:02,639 which is about fifty oh it may be fifty or 80 00:05:03,120 --> 00:05:08,639 greater quality green surfaces than used to exist in the sixties. 81 00:05:10,879 --> 00:05:13,800 It's way better since nineteen eighty than it ever was 82 00:05:13,839 --> 00:05:20,680 in nineteen seventy and even today it's getting better. So 83 00:05:21,519 --> 00:05:26,360 greens at country clubs and municipal golf courses and high 84 00:05:26,399 --> 00:05:30,879 dollar public golf courses or semi private golf courses they 85 00:05:30,920 --> 00:05:34,519 can all have a very high quality green surface that 86 00:05:34,680 --> 00:05:38,160 does not require us a lot of special speeding up 87 00:05:38,839 --> 00:05:45,519 for en global experiences. For example, everybody says bent grass 88 00:05:45,560 --> 00:05:50,480 is better than bermuda. In nineteen eighty one, Augusta, Georgia 89 00:05:50,879 --> 00:05:53,800 got rid of its bermuda grass and replaced it with 90 00:05:53,920 --> 00:05:58,120 bent grass because university researchers had designed the grass that 91 00:05:58,160 --> 00:06:03,519 would live in the hot and human South, and prior 92 00:06:03,519 --> 00:06:08,199 to nineteen eighty you couldn't grow bent grass in the Custa, Georgia. 93 00:06:08,439 --> 00:06:10,480 So as soon as they were able to grow a 94 00:06:10,680 --> 00:06:14,800 strain of engineered grass bent grass in Georgia, they ripped 95 00:06:14,800 --> 00:06:17,680 out all the permute and redid everything. And they found 96 00:06:17,680 --> 00:06:20,839 out that they're buried elephant grounds, and the greens of Augusta, 97 00:06:20,879 --> 00:06:24,319 Georgia were too steep for the quicker green speed. Remember 98 00:06:24,319 --> 00:06:27,639 it's a combination of the speed and the slope. And 99 00:06:27,720 --> 00:06:30,199 they had too much slope because they had old permuted 100 00:06:30,240 --> 00:06:33,360 greens with a lot of slope. And when they changed 101 00:06:33,360 --> 00:06:35,480 the bent greens, they had to get the bulldozers out 102 00:06:35,480 --> 00:06:39,720 and kind of flattened their elephants a little bit, all right. 103 00:06:39,800 --> 00:06:42,920 So they did the same thing with Pinehurst. You haven't 104 00:06:42,959 --> 00:06:45,920 seen a Donald Ross green because you can't have one today. 105 00:06:45,959 --> 00:06:48,079 The grass is too fast to allow that kind of 106 00:06:48,959 --> 00:06:51,680 crowning that he used to have. His were really crowned 107 00:06:51,720 --> 00:06:57,600 because they were slow. But the story continues into modern 108 00:06:57,639 --> 00:07:01,199 times because now they've gone full circle and now the 109 00:07:01,319 --> 00:07:04,959 highly engineered bermuda grasses or superior to the bent grasses. 110 00:07:06,199 --> 00:07:06,920 Speaker 1: That's interesting. 111 00:07:07,439 --> 00:07:13,079 Speaker 3: For example, Champions is a strain of highly engineered bermuda 112 00:07:13,120 --> 00:07:16,560 grass that you can pack and mow and get low 113 00:07:16,720 --> 00:07:21,079 and true, and it is more heat resistant than the 114 00:07:21,199 --> 00:07:25,560 special bent grasses of Augusta George in Greensboro, North Ohino. 115 00:07:25,639 --> 00:07:29,800 The PGA Tour just finished in the Wyndham Championship and 116 00:07:30,160 --> 00:07:34,240 a billionaire bought a bankrupt country club and the first 117 00:07:34,240 --> 00:07:36,319 thing he did was rip out all the bent greens 118 00:07:36,959 --> 00:07:43,079 and put in Champions dwarf Bermuda greens. And the golf 119 00:07:43,639 --> 00:07:49,279 professionals from PGA Tour exuded luxuriously about the wonderful condition 120 00:07:49,519 --> 00:07:51,839 of the greens at Wyndham Championship. 121 00:07:57,879 --> 00:08:00,800 Speaker 1: Do golf courses want to have their green as fast 122 00:08:00,879 --> 00:08:03,199 as they possibly can? Is that there. 123 00:08:05,160 --> 00:08:07,399 Speaker 3: There's a limit on you know, I mean, if you 124 00:08:07,439 --> 00:08:11,160 want to put on marble greens, not yourself out. There's 125 00:08:11,199 --> 00:08:14,120 a limit to you know, what is the challenge of 126 00:08:14,360 --> 00:08:22,560 golf in the outside of environment. So STEMP thirteen Oakmont 127 00:08:22,720 --> 00:08:27,439 is kind of silly. I mean, who wants to play that. 128 00:08:27,920 --> 00:08:31,240 It's interesting as a vacation, like going to Disneyland once, 129 00:08:31,639 --> 00:08:33,080 but you sure don't want to live there. 130 00:08:34,039 --> 00:08:35,879 Speaker 1: Yeah, but when you only play up to play there once, 131 00:08:35,960 --> 00:08:38,080 you're probably just going to get torture. 132 00:08:39,039 --> 00:08:40,960 Speaker 3: You won't come back, right, you won't. 133 00:08:40,960 --> 00:08:43,200 Speaker 1: You won't come back. You'll say, oh, I really want 134 00:08:43,240 --> 00:08:45,679 to play this game because now I finally after eighteen old, 135 00:08:45,720 --> 00:08:47,840 I finally got this bit. Yah, you ain't coming back. 136 00:08:48,559 --> 00:08:50,480 Speaker 3: You take pictures and everything, but you just you know, 137 00:08:50,679 --> 00:08:54,080 it's goofy. It's not really what the skill of the 138 00:08:54,120 --> 00:08:56,399 golf is all about. The skill of the golf is 139 00:08:57,000 --> 00:08:59,679 you know, it's a reasonable test. It's not a goofy 140 00:09:00,480 --> 00:09:04,759 buck based thing. There's a certain point where the green 141 00:09:04,799 --> 00:09:12,279 speed gets beyond controllable. The reads you just you're just 142 00:09:12,360 --> 00:09:14,600 shooting in the dark and making a read because you 143 00:09:14,639 --> 00:09:18,080 can't control your boss bet enough. And you it's the 144 00:09:18,200 --> 00:09:22,080 variation on what it will work is all over the map, 145 00:09:22,159 --> 00:09:24,919 and you know, you're three putton and all that kind 146 00:09:24,919 --> 00:09:29,240 of stuff, and downhill putts are crazy. So somewhere around 147 00:09:29,519 --> 00:09:35,399 stamp twelve, that's where you probably should stop. If you 148 00:09:35,440 --> 00:09:39,200 go past Stemp twelve, you're just you're just toying with 149 00:09:39,399 --> 00:09:40,360 wounded mice. 150 00:09:43,240 --> 00:09:46,320 Speaker 1: And if you're below what number is it like just 151 00:09:46,879 --> 00:09:48,559 you you need to just. 152 00:09:48,639 --> 00:09:54,000 Speaker 3: Add I would say it's today. In Europe, some of 153 00:09:54,000 --> 00:09:56,279 the greens are seven and a half feet on the 154 00:09:56,320 --> 00:10:00,039 Stemp meter, maybe seven on a bad day. They have 155 00:10:00,120 --> 00:10:04,679 some humidity problems. For example, in the Netherlands, it's pretty 156 00:10:04,720 --> 00:10:09,200 much below sea level and the grass is too moist. 157 00:10:09,639 --> 00:10:14,279 The soil is not draining well, and those grasses can 158 00:10:14,360 --> 00:10:18,000 be a little thin, and if they're thin, you got 159 00:10:18,039 --> 00:10:19,960 to kind of grow them tall in order to cover 160 00:10:20,000 --> 00:10:24,399 the green, and then it's not that great. So in 161 00:10:24,519 --> 00:10:31,000 Europe some of the greens are not suitable for really 162 00:10:31,080 --> 00:10:35,879 fast surfaces. As you get further towards the warmer climates, 163 00:10:36,039 --> 00:10:38,159 you can pick up some good greens. I would say 164 00:10:38,279 --> 00:10:43,519 Aldraama and places like that, you can have some really nice, 165 00:10:43,600 --> 00:10:47,080 really good greens. There's a lot of quality golf in Europe. 166 00:10:47,120 --> 00:10:51,320 Don't get me wrong, it's good I'm just saying that 167 00:10:51,320 --> 00:10:55,679 that seven point five on a meter, if you roll 168 00:10:55,679 --> 00:10:57,440 the ball off the bottom of a stent meter and 169 00:10:57,600 --> 00:10:59,799 only those two putter links and the plus a little 170 00:10:59,840 --> 00:11:04,279 bit further, that's not a great green. PGA tours typically 171 00:11:04,320 --> 00:11:08,879 are stimping eleven feet, which is a lot more than seven, 172 00:11:10,720 --> 00:11:15,039 and on a fast, challenging green, they can go up 173 00:11:15,039 --> 00:11:19,679 to twelve and thirteen. You don't want to US Opens. 174 00:11:19,720 --> 00:11:23,360 They're always trying to maximum maximize the green speed for 175 00:11:23,399 --> 00:11:27,840 some reason, because they're just torturous, cruel individuals that are 176 00:11:27,919 --> 00:11:33,559 testing golfers that you know can play lots of golf 177 00:11:33,600 --> 00:11:36,039 courses with high degree of success and they want to 178 00:11:36,080 --> 00:11:37,960 mess with that particular crowd. 179 00:11:38,240 --> 00:11:41,679 Speaker 1: Yes, well, that and growing the rough as thick as 180 00:11:41,720 --> 00:11:45,000 they possibly can, right, I mean, it's the hardest test 181 00:11:45,039 --> 00:11:48,840 in golf. It makes great golfers look like it's. 182 00:11:48,679 --> 00:11:53,200 Speaker 3: Not something that a normal golf would want to do. No, 183 00:11:53,240 --> 00:11:57,000 it's it's not really a golf It's the US Open golf, 184 00:11:57,039 --> 00:12:00,559 but it's not really what normal people will think of. 185 00:12:00,759 --> 00:12:04,919 Is off right Now, back to the limit on how 186 00:12:06,080 --> 00:12:09,759 much you can speed up the grass if you're green 187 00:12:09,919 --> 00:12:13,840 has been designed with x amount of slope. You can't 188 00:12:13,960 --> 00:12:17,200 put pen positions where you're going to speed it up 189 00:12:17,200 --> 00:12:21,399 to thirteen if that slope is too steep. And so 190 00:12:21,559 --> 00:12:25,279 all US Open golf course set up people have been 191 00:12:25,320 --> 00:12:31,000 given the so called Tom Meeks injunction with that Tom 192 00:12:31,159 --> 00:12:33,399 Tom Meeks is the guy that's screwed up. They set 193 00:12:33,519 --> 00:12:36,440 up three different times and they fired. They threw him 194 00:12:36,440 --> 00:12:40,480 out the window. It's called defenestration. Chuck you out the 195 00:12:40,519 --> 00:12:47,120 windows used to be popular in Florence in Dante's day 196 00:12:47,679 --> 00:12:50,440 with the medicis and all that, and sometimes they did 197 00:12:50,440 --> 00:12:53,200 it in the nineteen twenties New York with the mafia. 198 00:12:53,360 --> 00:12:55,399 But any rate, when they throw you out the window, 199 00:12:55,440 --> 00:12:58,600 that means they've had enough because you you messed up 200 00:12:58,840 --> 00:13:03,679 the US Open by putting the pin position on two 201 00:13:03,799 --> 00:13:06,480 great a slope and then you drove the speed of 202 00:13:06,519 --> 00:13:09,440 the surface up past the red line and the ball 203 00:13:09,519 --> 00:13:17,480 won't stop. It's called crazy golf and you look terrible 204 00:13:17,480 --> 00:13:23,039 on TV when the US Open is completely stupid. They 205 00:13:23,039 --> 00:13:25,720 did it at Shinnecock Hills, they did it at Southern Hills. 206 00:13:25,759 --> 00:13:30,879 They did an Olympic in San Francisco. It was it's 207 00:13:31,000 --> 00:13:34,720 just so. Now they have a little rule. If you're 208 00:13:34,720 --> 00:13:36,440 going to be the setup guy for the USJ and 209 00:13:36,480 --> 00:13:38,279 set up the US Open, it puts you in a 210 00:13:38,399 --> 00:13:41,120 room and they say you have one mission in life. 211 00:13:41,279 --> 00:13:48,120 Do not pull a tom meeks So. But anyway, so 212 00:13:48,600 --> 00:13:53,960 that that that combination of green speed and slope, there's 213 00:13:54,000 --> 00:13:58,559 a number. You can figure it out. The combination really 214 00:13:58,600 --> 00:14:03,000 needs another word. I call it the SS the slope stemp. 215 00:14:04,919 --> 00:14:08,480 So if you take the slope two percent and multiply 216 00:14:08,519 --> 00:14:11,840 at times the green speed stemp ten, a ball rolls 217 00:14:11,879 --> 00:14:14,200 off the stemp meter and rolls ten feet across the green, 218 00:14:15,080 --> 00:14:21,440 that would be a SS of twenty ten. The ball 219 00:14:21,480 --> 00:14:27,600 won't stop when the SS is sixty, okay, just in 220 00:14:27,679 --> 00:14:31,759 physicals just won't stay there, all right. It's like you 221 00:14:32,080 --> 00:14:34,279 tilt to the table so much that all the plates 222 00:14:34,279 --> 00:14:39,200 slid off, all right, Now, A sixty can be reached 223 00:14:39,200 --> 00:14:44,559 by any number of pathways a four slope four percent 224 00:14:44,639 --> 00:14:49,559 and a fifteen stemp green, or a twelve stemp green 225 00:14:49,879 --> 00:14:55,639 and a five percent slope, or a ten stemp green 226 00:14:55,840 --> 00:15:02,120 and a six percent slope. S Yeah, that works. No, 227 00:15:02,399 --> 00:15:07,399 do any of those combinations of slope steepness and green 228 00:15:07,440 --> 00:15:12,559 speed when multiplied together equals sixty. They're functionally equivalent ball 229 00:15:12,639 --> 00:15:13,919 and stop. Oh got it? 230 00:15:13,960 --> 00:15:14,320 Speaker 1: Okay? 231 00:15:15,519 --> 00:15:20,480 Speaker 3: Ten times six is sixty. Thy yep, Stemp ten green 232 00:15:20,840 --> 00:15:25,320 six percent slope ball won't stop. Four times fifteen is 233 00:15:25,360 --> 00:15:30,639 sixty a Stemp fifteen green, and a four percent slope 234 00:15:30,799 --> 00:15:35,279 ball won't stop. So four percent. If it's a faster 235 00:15:35,519 --> 00:15:38,679 green than a Stemp ten, a Stemp ten, you can 236 00:15:38,720 --> 00:15:40,559 tilt it all the way to six percent and it'll 237 00:15:40,600 --> 00:15:43,960 still it won't roll off. But when you speed up 238 00:15:43,960 --> 00:15:46,799 to a Stemp fifteen, you can only go to a 239 00:15:46,840 --> 00:15:51,559 four percent slope and then it'll roll off. Right. That's 240 00:15:51,600 --> 00:15:54,720 what happened to Augusta National. They're buried Elphin grounds are 241 00:15:54,720 --> 00:15:58,399 too steep and they've got a faster grass on their 242 00:15:58,440 --> 00:16:01,559 golf course green, and then they had to flatten out 243 00:16:01,559 --> 00:16:06,799 the greens. The tilt is permanent. The green speed comes 244 00:16:06,840 --> 00:16:07,600 and goes. 245 00:16:08,120 --> 00:16:10,320 Speaker 1: Oh interesting, yeah, of course. 246 00:16:10,399 --> 00:16:14,919 Speaker 3: Okay, So five times twelve a five percent slope, that's 247 00:16:14,960 --> 00:16:17,039 as far as you can go with a Stemp twelve 248 00:16:17,120 --> 00:16:21,919 green ten toms six. You can go to six percent 249 00:16:21,960 --> 00:16:26,039 when you keep it down to Stemp ten, So if 250 00:16:26,080 --> 00:16:28,639 you slow down you can have steep conter. But if 251 00:16:28,679 --> 00:16:30,480 you ever get to where you really want to go 252 00:16:30,559 --> 00:16:33,200 for the gusto on your green speed and you start 253 00:16:33,200 --> 00:16:36,120 getting a bow stamp ten and eleven and that sort 254 00:16:36,120 --> 00:16:40,240 of thing, your pen positions kind of shrink on the green. 255 00:16:40,639 --> 00:16:42,360 If you had an image of the green and you 256 00:16:42,399 --> 00:16:45,360 said where are all the alliable pen positions? The first 257 00:16:45,399 --> 00:16:49,440 question is how fast is your STEMP speed. STEMP ten 258 00:16:49,559 --> 00:16:52,879 has a lot more pennable positions on green X, then 259 00:16:52,960 --> 00:16:58,399 does stamp eleven. They start to evaporate and the steeper 260 00:16:58,399 --> 00:17:05,119 conters become unavailable wolf for pin positions. The USDA they 261 00:17:05,119 --> 00:17:07,920 have little programs in little charts they carry around to 262 00:17:08,359 --> 00:17:11,519 watch that, and then they get on their weather channel 263 00:17:11,559 --> 00:17:15,440 on the TV and on the internet and they start 264 00:17:15,480 --> 00:17:19,680 predicting the weather for Wednesday, Thursday, Friday, Saturday and Sunday 265 00:17:19,720 --> 00:17:22,440 to make sure that they're not going to get side 266 00:17:23,480 --> 00:17:29,000 ambushed by dry, hot, windy weather that makes the greenspeed 267 00:17:29,079 --> 00:17:33,119 go over the red line that happened at shintyk Killops. 268 00:17:35,039 --> 00:17:38,319 So they don't really want to get all that close 269 00:17:38,400 --> 00:17:40,200 to the borderline. They're going to keep away from a 270 00:17:40,240 --> 00:17:44,759 little bit, so they have an absolute red line in physics, 271 00:17:44,799 --> 00:17:47,960 and then they back away from that at ten to six, 272 00:17:48,440 --> 00:17:51,920 six is like the absolute limit. You don't want to 273 00:17:51,960 --> 00:17:54,240 get as close to that six as you can unless 274 00:17:54,279 --> 00:18:02,880 you're real sure about the weather. Let's talk about. 275 00:18:02,640 --> 00:18:07,279 Speaker 1: The the two putts right back to last show we 276 00:18:07,599 --> 00:18:08,880 got that's where we got started. 277 00:18:09,319 --> 00:18:11,640 Speaker 3: Okay, so I've created these two putts that you do 278 00:18:11,720 --> 00:18:14,759 that tells you a lot about green rings with two 279 00:18:15,000 --> 00:18:19,880 ten to actually face. Most are the ones you want 280 00:18:19,880 --> 00:18:22,559 to know, right, the ones and the ones that you 281 00:18:22,599 --> 00:18:24,960 can actually sink, those are the ones you want to 282 00:18:24,960 --> 00:18:28,680 focus on. So that's basically inside fifteen feet and for 283 00:18:28,720 --> 00:18:31,519 a lot of people inside end feet. And that's a 284 00:18:31,559 --> 00:18:34,480 simple putt without any funny conter. And it's flat from 285 00:18:34,519 --> 00:18:37,119 the ball to the hole, even though it's tilted. The 286 00:18:37,240 --> 00:18:39,799 surface is not wrinkled and bumpy. 287 00:18:40,359 --> 00:18:42,319 Speaker 1: It's flat, not necessarily level. 288 00:18:43,240 --> 00:18:45,920 Speaker 3: Yeah, it's not necessarily. It won't be level because that 289 00:18:45,960 --> 00:18:49,960 won't drain, so it will be tilted. But we're talking 290 00:18:50,000 --> 00:18:52,920 about the surfaces. If you ran your hand over it, 291 00:18:52,960 --> 00:18:57,039 is it one flat plane surface like a table. 292 00:18:57,799 --> 00:18:59,119 Speaker 1: So that means the ball is just going to go 293 00:18:59,200 --> 00:19:02,039 straight from where you are to the well. 294 00:19:02,079 --> 00:19:04,799 Speaker 3: It just means that the break is highly predictable because. 295 00:19:04,480 --> 00:19:07,880 Speaker 1: It's not break is highly predictable as opposed to straight Okay. 296 00:19:08,480 --> 00:19:13,599 Speaker 3: Okay, complicated breaks they go across across different contours other 297 00:19:13,640 --> 00:19:18,039 than one flat plane, and those are more difficult to 298 00:19:18,519 --> 00:19:22,920 predict and to read and to execute. So we have 299 00:19:22,960 --> 00:19:27,279 a simple case. The simple case is, for example, a 300 00:19:27,359 --> 00:19:30,559 ten foot putt across flat green on a tilt that 301 00:19:30,680 --> 00:19:34,400 you run into all the time. What's the break? How 302 00:19:34,480 --> 00:19:37,720 much does it break? All right? So I've designed two 303 00:19:37,799 --> 00:19:41,960 little putts to tell you all about it. Let me 304 00:19:42,039 --> 00:19:45,839 describe it. Okay, okay, this is like a diamond bullet 305 00:19:45,880 --> 00:19:50,000 to the forward version of what I'm talking about. You 306 00:19:50,119 --> 00:19:54,079 find a two percent slope we've already described. How do 307 00:19:54,119 --> 00:19:56,519 you know it's two percent? Walk straight down till one 308 00:19:56,599 --> 00:19:59,799 hundred inches away you can go, and then you stop, 309 00:19:59,839 --> 00:20:01,680 and you compare where your foot is to where the 310 00:20:01,680 --> 00:20:04,440 hole is, and what's the elevation drop from the hole 311 00:20:04,519 --> 00:20:07,240 to your foot. You imagine a string coming out of 312 00:20:07,279 --> 00:20:10,079 the whole dead level and it as far as your 313 00:20:10,079 --> 00:20:12,640 foot and hide the string above your foot tells you 314 00:20:12,680 --> 00:20:15,559 how many inches it is to the surface. That's what 315 00:20:15,720 --> 00:20:18,960 percent the slope is. If the string hits your foot 316 00:20:19,000 --> 00:20:21,720 at two inches off the ground, it's a two percent 317 00:20:21,759 --> 00:20:25,119 slope because you went one hundred inches downhill. Two percent 318 00:20:25,359 --> 00:20:28,839 is too over one hundred it's a drop or rise 319 00:20:28,880 --> 00:20:31,720 of two inches of very run of one hundred inches. 320 00:20:32,160 --> 00:20:37,039 That's the slope percent. It's also called the grade. If 321 00:20:37,039 --> 00:20:39,319 the string inch your foot at three inches off the 322 00:20:39,359 --> 00:20:43,559 ground and that's a three percent slope. If the level 323 00:20:43,599 --> 00:20:45,160 string from the hole to your foot hits you in 324 00:20:45,200 --> 00:20:47,279 the ankle, that's a four percent slope. 325 00:20:47,400 --> 00:20:49,400 Speaker 1: So what we have to figure out is once we 326 00:20:49,480 --> 00:20:52,200 know what the slope is, once we know the degree is, 327 00:20:52,839 --> 00:20:55,240 we have to figure out how to adjust our speed. 328 00:20:55,359 --> 00:20:58,759 Speaker 3: Right, We're going to test a two percent slope on 329 00:20:58,799 --> 00:21:04,640 the livery speed. Okay, here's the next component. The things 330 00:21:04,640 --> 00:21:09,240 that make up break in physics are basically the steepness, 331 00:21:11,119 --> 00:21:17,039 the green speed, the distance of the putt, the conjuring 332 00:21:17,480 --> 00:21:20,440 or the flatness of the surface, and your ball delivery 333 00:21:20,480 --> 00:21:24,240 speed across that surface. How fast is the ball traveling 334 00:21:24,240 --> 00:21:25,720 when it gets to the front lift of the cup. 335 00:21:25,759 --> 00:21:29,720 That's called a terminal velocity or a delivery speed. Those 336 00:21:29,799 --> 00:21:37,000 factors steepness, also direction uphill, flatness of surface, speed of grass, 337 00:21:37,240 --> 00:21:40,119 how far away you're putting, and what is your delivery speed? 338 00:21:40,799 --> 00:21:45,799 You can fix all of those and sort them out, 339 00:21:46,400 --> 00:21:49,440 and the only thing left is how much will it break? 340 00:21:50,359 --> 00:21:53,240 All right, that's like fixing the variables so that you 341 00:21:53,240 --> 00:21:56,000 don't have to deal with ten variables. You have just one. 342 00:21:56,799 --> 00:21:58,720 It's like an experiment. That's what you do when you 343 00:21:58,759 --> 00:22:01,680 do experiments. So we're going to fix all the variables. 344 00:22:01,720 --> 00:22:04,920 Here's one, it's flat. Okay, we've decided we found a 345 00:22:04,960 --> 00:22:07,799 flat piece of grass. It's at least ten feet away 346 00:22:07,799 --> 00:22:11,240 from a hole. It doesn't change contours. Flat number two. 347 00:22:11,319 --> 00:22:15,440 What's the slope we found out it's percent number three. 348 00:22:15,759 --> 00:22:19,359 What's the green speed? It's today's green speed. If you 349 00:22:19,400 --> 00:22:23,640 want to know for mathematical calculations, you need to know 350 00:22:23,720 --> 00:22:26,160 the st meter speed of the green and so you 351 00:22:26,240 --> 00:22:27,960 have to ask somebody to nose or else you have 352 00:22:28,000 --> 00:22:29,839 to under meter. Else you have to know how to 353 00:22:29,839 --> 00:22:32,400 make one or use how to have to know how 354 00:22:32,440 --> 00:22:37,200 to simulate one. Basically, if you swing a conventional hutter 355 00:22:37,240 --> 00:22:39,720 about fifteen inches back from the ball and then let 356 00:22:39,720 --> 00:22:43,599 it re swing itself without you powering it, that will 357 00:22:43,599 --> 00:22:46,319 deliver the velocity of the ball that a STMP meter 358 00:22:46,440 --> 00:22:48,319 gets it off the bottom of the ramp. It's about 359 00:22:48,319 --> 00:22:54,440 the same if you get to two shafts and you 360 00:22:54,480 --> 00:22:56,400 make a little camel out of the two shafts by 361 00:22:56,440 --> 00:22:58,839 holding them together, and then you put a ball on 362 00:22:59,680 --> 00:23:02,000 the shape and you lift the ball up about ten 363 00:23:02,039 --> 00:23:04,160 and a half to eleven inches off the ground and 364 00:23:04,200 --> 00:23:07,680 then let go. It'll roll down the two shafts through 365 00:23:07,680 --> 00:23:10,119 the little channel you made, and then when it comes 366 00:23:10,119 --> 00:23:12,400 off it'll be about the same speed as the STEMP meter. 367 00:23:14,079 --> 00:23:15,759 Or you can buy a step meter, or you can 368 00:23:15,799 --> 00:23:18,599 just ask the greens keeper or the pro shop what's 369 00:23:18,599 --> 00:23:21,039 the stemp the green speed? Plus the golf courses will 370 00:23:21,079 --> 00:23:24,000 push a little sign out by the green. Today's green 371 00:23:24,119 --> 00:23:28,839 is stimping nine point five, so that. 372 00:23:28,799 --> 00:23:30,799 Speaker 1: Would be obviously that would be the easiest way to 373 00:23:30,799 --> 00:23:34,119 do it is just ask. But I'm sure there are there. 374 00:23:34,160 --> 00:23:38,920 There are so many different gadgets and and and apps 375 00:23:38,920 --> 00:23:41,119 for their phone and stuff that's going to help you 376 00:23:41,240 --> 00:23:44,119 determine this and are are they worth. 377 00:23:43,960 --> 00:23:48,000 Speaker 3: What this is? One that doesn't really the apps don't 378 00:23:48,000 --> 00:23:50,880 tell you the green speed. You have to you have 379 00:23:50,960 --> 00:23:55,240 to input that one, okay, all right. The apps will 380 00:23:55,279 --> 00:23:57,960 tell you which way is uphill and how steep is it? 381 00:23:59,240 --> 00:24:01,039 It won't really say see how flat it is? And 382 00:24:01,079 --> 00:24:02,319 I want to tell you the green speed, and I 383 00:24:02,319 --> 00:24:04,839 want to tell your ball delivery speed. Those you have 384 00:24:04,920 --> 00:24:07,440 to input, and it doesn't tell you how far you 385 00:24:07,480 --> 00:24:10,759 are away from the hall, all right, So we're sorting 386 00:24:10,799 --> 00:24:12,799 out all of these how far away we're going to 387 00:24:12,880 --> 00:24:17,640 be ten feet? That's four military paces each military pace 388 00:24:17,799 --> 00:24:22,079 thirty inches or US parade looks like crap, everybody, So 389 00:24:22,160 --> 00:24:24,000 you have to make a thirty inch step to and 390 00:24:24,039 --> 00:24:26,680 a half feet each. Four of those ten feet walk 391 00:24:26,759 --> 00:24:28,680 four feet away from the hall. Your ten feet away 392 00:24:29,119 --> 00:24:35,000 were three four steps away, all right. Now, we would 393 00:24:35,160 --> 00:24:39,720 like conveniently to have a stamp speed of the green 394 00:24:40,599 --> 00:24:45,720 that is ten for easy division. So we really want 395 00:24:45,720 --> 00:24:49,759 to STEMP ten green if we can find it. All right. 396 00:24:50,240 --> 00:24:52,240 So let's say we got a STEMP ten green two 397 00:24:52,240 --> 00:24:55,519 percent slow flat, and we're ten feet away, and we 398 00:24:55,599 --> 00:24:58,480 know which way is directly uphill straight through the hall, 399 00:24:59,279 --> 00:25:03,920 and we chose specifically to go ten feet away side 400 00:25:04,000 --> 00:25:07,839 hill or perpendicular to the direction straight up hill. If 401 00:25:07,839 --> 00:25:10,279 you have a clock and you twist it around so 402 00:25:10,400 --> 00:25:13,519 that the six and the twelve through the hole. The 403 00:25:13,559 --> 00:25:15,720 center of the clock is on the center of the hole, 404 00:25:15,759 --> 00:25:19,519 and the six and twelve points straight up hill. We're 405 00:25:19,519 --> 00:25:23,799 talking about walking along the line towards the three or 406 00:25:23,880 --> 00:25:29,319 the nine perpendicular to the six trove line. The nine 407 00:25:29,359 --> 00:25:33,759 to three line would be the axis of tilt. The 408 00:25:33,839 --> 00:25:37,759 direction of the of the surface is six twelve, and 409 00:25:37,839 --> 00:25:42,559 the steepness is how much the twelve wise it up 410 00:25:42,599 --> 00:25:47,359 over top of the six, or how steep the differences 411 00:25:47,480 --> 00:25:51,119 between the hole and the spot down the six one 412 00:25:51,200 --> 00:25:55,119 hundred inches away. What's the elevation drop from the hole 413 00:25:55,279 --> 00:26:00,279 to the six one hundred inches away. That's the steepness. Okay, 414 00:26:00,279 --> 00:26:03,839 so we've got a two percent grade for steepness. We 415 00:26:03,920 --> 00:26:09,880 have a flat green, we have a st ten, and 416 00:26:09,920 --> 00:26:13,680 we have a side hill ten foot putt. Now here's 417 00:26:13,799 --> 00:26:18,559 what you do with it. You put straight at the 418 00:26:18,599 --> 00:26:23,720 middle of the hole for start line with your normal 419 00:26:24,000 --> 00:26:29,440 delivery speed, and then everything is perfectly sorted. The ball 420 00:26:29,480 --> 00:26:32,720 will not go straight because it will curl downhill. If 421 00:26:32,759 --> 00:26:35,480 you're from the three putting, it will curl downhill towards 422 00:26:35,519 --> 00:26:39,200 the six to your left. If you're putting from the 423 00:26:39,319 --> 00:26:42,519 nine position, it will curl downhill to the sixth position 424 00:26:42,680 --> 00:26:46,079 from your to the right. Let's say we're at the 425 00:26:46,079 --> 00:26:48,839 three o'clock position, and we came dead straight at the 426 00:26:48,839 --> 00:26:51,839 center of the hall, and we putt it with good 427 00:26:51,960 --> 00:26:56,200 delivery pace, the ball will curl low and then it 428 00:26:56,240 --> 00:26:59,119 will cross the six to twelve line, and then it 429 00:26:59,160 --> 00:27:03,759 will stop very soon thereafter, because you have a good 430 00:27:03,759 --> 00:27:07,920 delivery pace. A good delivery pace will carry the ball 431 00:27:08,200 --> 00:27:12,480 past the six twelve line no more than one to 432 00:27:12,720 --> 00:27:17,160 four further rolls. Every roll over golf ball is about 433 00:27:17,200 --> 00:27:21,240 five point two eight inches. That's the diameter of the 434 00:27:21,359 --> 00:27:24,920 cover material of a ball one point six eight inches 435 00:27:24,960 --> 00:27:29,119 in diameter. Just one point six eight times pie equals 436 00:27:29,200 --> 00:27:33,200 five point two eight So if you unrolled the ball 437 00:27:33,319 --> 00:27:35,519 and lay it down like a ruler on the ground, 438 00:27:36,160 --> 00:27:38,519 it goes as far as the spin of your hand 439 00:27:38,839 --> 00:27:42,480 from the wrist line to the last knuckle, not the 440 00:27:42,519 --> 00:27:47,119 tip the last knuckle. That's five about five and a 441 00:27:47,200 --> 00:27:50,640 quarter inches. So if you patch your hands along past 442 00:27:50,960 --> 00:27:55,839 the fall line, one to three of those, that's about 443 00:27:56,240 --> 00:28:01,000 the same as a guinea inside the leather. If you 444 00:28:01,160 --> 00:28:04,359 climbed your hands up a putter from the putter head 445 00:28:04,440 --> 00:28:07,000 to the bottom of the grip material, you'd have about 446 00:28:07,039 --> 00:28:09,920 three handspans and then it's the bottom of the grip material. 447 00:28:10,240 --> 00:28:15,160 So inside the leather is approximately three rolls past the 448 00:28:15,240 --> 00:28:20,039 hull or the falling Okay, Four, you're still in the leather, 449 00:28:20,160 --> 00:28:24,640 so that's not terrible. Five you're outside the leather. And 450 00:28:24,680 --> 00:28:29,160 now you're talking about three putty. 451 00:28:29,359 --> 00:28:33,720 Speaker 1: We don't like to talk about three putty. Oh we 452 00:28:33,799 --> 00:28:42,720 lost you. Oh my god, I can't believe this. We 453 00:28:42,839 --> 00:28:46,039 lost our signal just as you said that's when you 454 00:28:46,079 --> 00:28:50,279 three putty. I'd be like, well, what this is like 455 00:28:50,359 --> 00:28:52,519 a joke. I'm supposed to guess something here, but we 456 00:28:52,599 --> 00:28:55,200 lost our connection. So I'm glad that we're back. You're 457 00:28:55,279 --> 00:28:58,480 still at McDonald's. Is now probably very dark? Were you 458 00:28:58,559 --> 00:29:02,759 when we've bet this for a while? So finish your sentence. Yes, 459 00:29:02,839 --> 00:29:05,000 we don't want a three put So where are we? 460 00:29:05,079 --> 00:29:07,799 Speaker 3: Ok So, we were just we were just we were 461 00:29:07,880 --> 00:29:10,480 just locking down the variables, one of which is touch. 462 00:29:11,720 --> 00:29:14,960 We want to putt our test putt to find out 463 00:29:15,000 --> 00:29:20,200 the break using our usual good touch delivery speed that 464 00:29:20,359 --> 00:29:23,240 only goes one, two or three rolls past the fall 465 00:29:23,279 --> 00:29:26,839 line in case of a miss, and then the ball 466 00:29:26,920 --> 00:29:30,720 stops right. So if you have that skill, you use 467 00:29:30,799 --> 00:29:34,559 that touch delivery speed when we do this ten foot 468 00:29:34,599 --> 00:29:38,720 test putt. Right now, we got all everything sort. Now 469 00:29:38,839 --> 00:29:41,640 we just do is we make a straight putt directly 470 00:29:41,680 --> 00:29:45,359 at the hole with good touch, and then we watch 471 00:29:45,559 --> 00:29:49,240 and see how far it crosses the fall line below 472 00:29:49,279 --> 00:29:54,839 the center of the hole. And we measure all Right, if, 473 00:29:54,839 --> 00:29:58,440 for example, a two percent slope and a stemp tin 474 00:29:58,559 --> 00:30:02,359 green with your good deliver every speed started straight at 475 00:30:02,359 --> 00:30:08,079 the hole curls ten inches below the hole. Guess what 476 00:30:09,400 --> 00:30:14,960 ten inches divided by ten foot putt tells you the 477 00:30:15,000 --> 00:30:20,200 magic number. It tells you that that surface combination a 478 00:30:20,319 --> 00:30:25,039 twenty of a Stemp ten green and this two percent 479 00:30:25,119 --> 00:30:30,200 slope multiplied together as a stemp slope something called twenty 480 00:30:30,359 --> 00:30:35,519 twenty breaks one inch for every foot that you putt it. 481 00:30:35,720 --> 00:30:38,839 Remember it broke ten inches when it crossed the fall 482 00:30:38,880 --> 00:30:41,519 line below the center of the hall. It was ten 483 00:30:41,559 --> 00:30:44,119 inches from the center of the hole to the point 484 00:30:44,119 --> 00:30:48,839 where the battrolled across the falling We measured it was 485 00:30:48,920 --> 00:30:52,839 one grip the length of one putter grip from the 486 00:30:52,839 --> 00:30:54,519 center of the hole to the point where the ball 487 00:30:54,599 --> 00:31:00,400 rolled across low beneath the hole across that fallen petted 488 00:31:00,480 --> 00:31:05,079 from ten feet away. So if you divide the number 489 00:31:05,079 --> 00:31:07,880 of inches that it breaks, and by end I mean 490 00:31:08,039 --> 00:31:13,839 the stemp slope twenty, it broke one inch for every 491 00:31:13,920 --> 00:31:17,720 foot that you were away from the hole. Right, that's 492 00:31:17,839 --> 00:31:20,480 the magic. Now you can you can You can aim 493 00:31:20,519 --> 00:31:22,680 a fifteen footer, you can name a five footer. You 494 00:31:22,680 --> 00:31:28,039 canna an eight footer. And the next point is those 495 00:31:28,079 --> 00:31:30,400 are all the side hill putts. You can aim all 496 00:31:30,440 --> 00:31:34,039 of those based on that formula one inch per foot 497 00:31:34,119 --> 00:31:40,759 for stemp speed twenty slope speed twenty, they're all one 498 00:31:40,799 --> 00:31:47,759 inch per foot. A five foot put breaks five inches. Okay, 499 00:31:48,920 --> 00:31:51,400 on a twenty if you aim from the center of 500 00:31:51,440 --> 00:31:55,240 the hall five inches straight up hill and stick a 501 00:31:55,319 --> 00:31:59,759 teepeg again and start your ball directly at the teepeg 502 00:31:59,799 --> 00:32:02,039 and let it break to the low side, it will 503 00:32:02,079 --> 00:32:04,200 go in the center of the cup if you hit 504 00:32:04,880 --> 00:32:10,799 the same delivery pace that you use to test it with. Now, 505 00:32:10,839 --> 00:32:13,759 if you use a eight foot put breaks eight inches, 506 00:32:13,960 --> 00:32:16,079 you need to get that now. I just need to 507 00:32:16,079 --> 00:32:23,839 stop them talk talk to them later. So now those 508 00:32:23,880 --> 00:32:28,920 are side hipputs. Now here's the next point. If you 509 00:32:29,000 --> 00:32:32,720 wanted to know ten feet putt around the center of 510 00:32:32,759 --> 00:32:36,559 the hall in a big circle. You took a ten 511 00:32:36,599 --> 00:32:38,319 foot string and stuck it right in the middle of 512 00:32:38,359 --> 00:32:40,759 the center of the cup, and then you stretched it 513 00:32:40,799 --> 00:32:43,359 out ten feet away, and you drew a circle around 514 00:32:43,519 --> 00:32:47,480 the cup ten feet out, and you put three hundred 515 00:32:47,480 --> 00:32:50,400 and sixty golf balls on that circle, in a big circle, 516 00:32:50,440 --> 00:32:53,079 and you put it every single one of them. They 517 00:32:53,119 --> 00:32:57,599 aim at exactly the same target ten inches above the hole. 518 00:32:58,440 --> 00:33:01,960 The teepegg on the fall line, ten inches from the 519 00:33:01,960 --> 00:33:06,480 center of the cup. The uphill puts same in it. 520 00:33:06,519 --> 00:33:08,640 The downhill putts ame at it, the todd hill putts 521 00:33:08,640 --> 00:33:10,720 seam at it. They all aim at that one te peg. 522 00:33:12,279 --> 00:33:14,440 And then they eight foot putt they aim at a 523 00:33:14,480 --> 00:33:16,920 t peg eight inches above the hole. And a five 524 00:33:16,920 --> 00:33:19,119 foot putt they am at a t peg five inches 525 00:33:19,119 --> 00:33:23,640 above the hole. Now, some people will say funny stuff 526 00:33:23,680 --> 00:33:25,759 about that, and they will say that downhill putts go 527 00:33:25,880 --> 00:33:29,160 more slowly and they break more, and they'll pill putts 528 00:33:29,200 --> 00:33:33,160 go faster and they break less. Well, that's the difference 529 00:33:33,200 --> 00:33:36,559 between academic people that never get outside their office and 530 00:33:36,640 --> 00:33:37,720 people who play off. 531 00:33:38,119 --> 00:33:41,559 Speaker 1: Go ahead. We've been doing this twice for almost two 532 00:33:41,559 --> 00:33:42,599 hours ago, and you haven't said it. 533 00:33:42,640 --> 00:33:46,400 Speaker 3: Come on, say it, rough and rap Scots have contempt 534 00:33:46,440 --> 00:33:47,640 for academics in there. 535 00:33:47,720 --> 00:33:50,519 Speaker 1: Oh no, man, those people are stupid. Come on say it. 536 00:33:50,920 --> 00:33:51,720 Speaker 3: They're stupid. 537 00:33:52,599 --> 00:34:00,599 Speaker 4: They got PhDs and it means fud dummy. They right papers, 538 00:34:00,799 --> 00:34:05,240 and they have all kinds of pretensions to mathematical expertise 539 00:34:05,400 --> 00:34:08,760 and physics degrees and blah blah blah blah blah. Well 540 00:34:08,920 --> 00:34:12,039 they ain't a patch on my ass because I got 541 00:34:12,079 --> 00:34:13,719 forty years of loving physics. 542 00:34:13,760 --> 00:34:18,320 Speaker 3: But I know golf. They don't know golf. Bad combination. 543 00:34:19,639 --> 00:34:21,800 It's like they know how to mixed paint, but they 544 00:34:21,920 --> 00:34:29,159 never painted house. Okay, you can't apply physics to golf 545 00:34:29,360 --> 00:34:31,719 unless you know the golf. Let me say that one 546 00:34:31,719 --> 00:34:35,360 more time. I don't care if you can do the formulas, 547 00:34:35,519 --> 00:34:39,400 old physics guy at Yale, you don't know how it 548 00:34:39,480 --> 00:34:43,400 applies to the golf course because we're roughing round a Scotch. 549 00:34:43,440 --> 00:34:47,320 We're engineers. We're not calculators trying to get a in 550 00:34:47,360 --> 00:34:51,400 a classroom. We're engineers making a putt go in a hole. 551 00:34:52,159 --> 00:34:55,679 There's a little sloppiness at all, all right, So what 552 00:34:55,800 --> 00:34:59,599 we want to do is bushwhack common putts, And once 553 00:34:59,599 --> 00:35:02,440 you find that is that. Yeah, there is a technical 554 00:35:02,480 --> 00:35:05,599 difference between a downhill putt and uphill putt, but it 555 00:35:05,679 --> 00:35:10,360 doesn't really matter until you get a steep green of 556 00:35:10,679 --> 00:35:15,440 three percent or more and you get passed beyond further 557 00:35:15,599 --> 00:35:20,159 than ten feet. It just doesn't it's not that big 558 00:35:20,199 --> 00:35:23,760 of a difference. Now, the guys in their eye retires 559 00:35:23,760 --> 00:35:26,880 that calculate that if you look back at their notebooks, 560 00:35:26,960 --> 00:35:29,800 they will find out that their little differences aren't that 561 00:35:29,960 --> 00:35:34,079 big until you get beyond this realm of reality. So 562 00:35:34,119 --> 00:35:36,079 we take the stage and we kick them off the 563 00:35:36,119 --> 00:35:38,280 stage and we embarrass them in front of their peers 564 00:35:38,320 --> 00:35:40,960 because they act like they know stuff, but they're basically 565 00:35:41,159 --> 00:35:47,920 bad scientists. They can't apply knowledge, so that makes them 566 00:35:47,960 --> 00:35:52,039 bad scientists to purport to answer questions in golf and 567 00:35:52,159 --> 00:35:54,760 they don't know anything about the golf. They need to 568 00:35:54,880 --> 00:35:59,519 shut up and stop. It's not a diletent sport where 569 00:35:59,519 --> 00:36:02,440 you can come in and lord other people because you've 570 00:36:02,440 --> 00:36:06,760 got a pH d at Yale University. Go away. There 571 00:36:06,800 --> 00:36:10,159 are people that know more about it than you. They 572 00:36:10,159 --> 00:36:15,400 are scientists that apply the knowledge intelligently. And reasonably to 573 00:36:15,599 --> 00:36:19,800 the actual experience of golfers on real greens, about which 574 00:36:19,920 --> 00:36:23,559 at Yale and have in Connecticut they know very darned little. 575 00:36:24,039 --> 00:36:27,079 Speaker 1: Now you know you it not let Yale specific like 576 00:36:27,119 --> 00:36:28,159 you don't like Harvard either. 577 00:36:28,679 --> 00:36:31,760 Speaker 3: Another there's one guy to that write these papers. There's 578 00:36:31,760 --> 00:36:34,880 another guy at Malespi University in British Columbia that writes 579 00:36:34,960 --> 00:36:37,159 these papers. And there's another guy that say, as they 580 00:36:37,199 --> 00:36:41,840 stay and I call them play papers. Want to embarrass 581 00:36:41,880 --> 00:36:44,960 them with their with their peers and physics, because their 582 00:36:44,960 --> 00:36:48,440 peers in physics know that they don't count that they're 583 00:36:48,440 --> 00:36:51,119 not going to make money or get an advancement in 584 00:36:51,159 --> 00:36:54,039 their physics department by writing these little papers. And they 585 00:36:54,039 --> 00:36:57,519 have two weeks off in the summer, and this is 586 00:36:57,679 --> 00:36:59,760 something to go for them to come in and pretend 587 00:36:59,800 --> 00:37:05,440 to do that. It looks a lot more significant to 588 00:37:05,480 --> 00:37:10,559 golfers than it should. But an educated, rough and rowdy 589 00:37:10,719 --> 00:37:16,920 Scott's engineer has contempt for this sort of thing. Okay, 590 00:37:17,239 --> 00:37:18,920 value of the game got too much to allow that 591 00:37:19,000 --> 00:37:22,320 kind of silliness. So we tell the people that yell 592 00:37:22,440 --> 00:37:27,480 and malice being and sentas a stick it stop, go away. 593 00:37:28,000 --> 00:37:29,960 We're going to explain to our friends of the golfers 594 00:37:30,000 --> 00:37:34,239 that you're not there, buddy, that you don't really know 595 00:37:34,320 --> 00:37:39,039 what you're doing. Okay, now back to the test put. 596 00:37:40,559 --> 00:37:43,599 When you apply all this, it has a difference between 597 00:37:43,639 --> 00:37:46,199 danielfo It doesn't matter, does not until you get sleep 598 00:37:46,239 --> 00:37:48,239 and you get far away and we're not there, not 599 00:37:48,360 --> 00:37:54,159 makable pus anyway. So yeah, it is a difference. But 600 00:37:54,960 --> 00:37:57,559 when you're in the cleanup done, man, a five foot 601 00:37:57,599 --> 00:38:01,199 put from any direction, you're you're read to lock and 602 00:38:01,280 --> 00:38:04,440 load if you know that five foot breaks five inches, 603 00:38:06,039 --> 00:38:07,559 and that's on the twenty. So you got to know 604 00:38:07,599 --> 00:38:11,079 whether you're on a twenty or not. Now you can 605 00:38:11,119 --> 00:38:15,800 get the twenties by different ways. A stamp saturn and 606 00:38:15,880 --> 00:38:23,039 a three percent slope is about twenty. A stamp eleven 607 00:38:23,320 --> 00:38:27,760 and a stamp what makes it twenty two one and 608 00:38:27,840 --> 00:38:31,119 a half or some one point sat and something like that. 609 00:38:31,840 --> 00:38:35,239 Whatever whatever calculator tells you, I can't. 610 00:38:34,960 --> 00:38:37,960 Speaker 4: Do it in my head, you know, I gotta admit that. 611 00:38:38,239 --> 00:38:42,639 Speaker 3: But any combination where it comes out of twenty, they 612 00:38:42,679 --> 00:38:47,000 break exactly the same. Wow. Yeah, that's cool. 613 00:38:47,480 --> 00:38:49,119 Speaker 1: That revelation stuff. 614 00:38:49,119 --> 00:38:52,679 Speaker 3: That's awesome. That's right now, they've done this since at 615 00:38:52,760 --> 00:38:54,719 least in nineteen eighty four, because it's nice. Little guy 616 00:38:54,760 --> 00:38:56,920 in Texas as a retired Air Force colonel and at 617 00:38:57,079 --> 00:39:01,639 Tempson put it in his book. So anybody that's supports 618 00:39:01,679 --> 00:39:05,000 today be the originator of this. That would not include me, 619 00:39:05,000 --> 00:39:09,280 because I'm respectful in honor of the past. However, there 620 00:39:09,320 --> 00:39:12,039 are other people who act as if they came up 621 00:39:12,079 --> 00:39:17,199 with it. Well they did, by golly all right. 622 00:39:17,239 --> 00:39:24,639 Speaker 5: So these magnificent concepts of slope and Stemp meter smashed together, 623 00:39:25,079 --> 00:39:29,199 mash up into a new thing called the something, the 624 00:39:29,239 --> 00:39:30,760 Stemp slope SS. 625 00:39:32,440 --> 00:39:35,239 Speaker 3: It doesn't matter how you get there. If you recognize 626 00:39:35,280 --> 00:39:37,599 it's a twenty, you're off to the races on knowing 627 00:39:37,599 --> 00:39:40,440 what you're doing. Right now, let's go to the next level. 628 00:39:40,719 --> 00:39:42,639 Speaker 1: Wait wait, wait, wait, wait wait wait wait, are you playing 629 00:39:42,639 --> 00:39:45,400 with that power thing again? Because your signal got better? 630 00:39:46,360 --> 00:39:47,480 Speaker 3: Okay, I stopped it. 631 00:39:47,559 --> 00:39:49,639 Speaker 1: Yeah, but as you were doing that, the signal got 632 00:39:50,079 --> 00:39:50,639 much better. 633 00:39:51,079 --> 00:40:01,920 Speaker 3: Okay, now cool, Okay, we know from one putt, one symbol, 634 00:40:02,159 --> 00:40:06,039 one single symbol, simple little putt, a ten foot putt 635 00:40:06,079 --> 00:40:11,519 on a two percent slope, STEMP ten green, it's a twenty. 636 00:40:12,320 --> 00:40:14,679 We made a ten foot putt, and we've found out 637 00:40:15,559 --> 00:40:20,800 something magical that sorts out everything inside fifteen feet for 638 00:40:20,960 --> 00:40:27,119 that particular twenty, right, we did as one putt. Now 639 00:40:27,199 --> 00:40:31,639 let's go over the top and expand it to many 640 00:40:31,760 --> 00:40:35,719 other slopes that we might actually encounter a one percent 641 00:40:35,800 --> 00:40:39,559 of three percent, four percent, five percent, six percent. We 642 00:40:39,599 --> 00:40:44,480 did a twenty, which means for that green speed, a 643 00:40:44,639 --> 00:40:49,760 two is proportionately what in relationship to a one twice 644 00:40:49,760 --> 00:40:53,000 a month as much. So. That means if it broke 645 00:40:53,239 --> 00:40:57,239 one inch on a two percent stemp ten green, we 646 00:40:57,360 --> 00:41:00,599 now know that on a one percent slope it will 647 00:41:00,639 --> 00:41:05,880 break one half of an inch. Now we have the 648 00:41:06,039 --> 00:41:09,679 entire world of one percent slopes in our little bailliwick. 649 00:41:11,199 --> 00:41:15,400 Let's put the threes in there. A three percent slope 650 00:41:15,599 --> 00:41:19,760 will break one point five times as much as the 651 00:41:19,800 --> 00:41:25,079 two percent. That means the two percent breaks one inch. 652 00:41:25,960 --> 00:41:29,360 A three percent will break one point five inches for 653 00:41:29,519 --> 00:41:33,119 every foot of putt you're five feet away, how much 654 00:41:33,199 --> 00:41:36,800 is it gonna break seven and a half inches. That's 655 00:41:36,880 --> 00:41:42,039 five times one point five that's just three percent slope. Okay, 656 00:41:42,239 --> 00:41:44,639 how much is ten percent ten foot canna breaking on 657 00:41:44,719 --> 00:41:49,199 three percent slope? Fifteen inches ten times one point five. 658 00:41:50,840 --> 00:41:53,440 All right, So we have three percent slopes now in 659 00:41:53,519 --> 00:41:56,960 our balliwick, let's do four. What's the relationship between the 660 00:41:57,039 --> 00:42:00,000 two percent slope and four percent slope? Twice as much? 661 00:42:01,800 --> 00:42:04,840 So a four percent slope will break two inches for 662 00:42:04,920 --> 00:42:10,239 every foot. A ten foot putt will break twenty inches 663 00:42:11,519 --> 00:42:13,679 from the center of the hall straight up. He'll put 664 00:42:13,679 --> 00:42:16,800 a tepeg in two putter grips up and then putt 665 00:42:16,800 --> 00:42:19,199 with your good delivery speed straight at that tepeg and 666 00:42:19,280 --> 00:42:23,559 let it break straight and soon the hole. A five 667 00:42:23,639 --> 00:42:27,280 foot putt will break ten inches because it's two foot 668 00:42:27,360 --> 00:42:31,400 two inches for every foot, and you got five of them. Now, 669 00:42:31,440 --> 00:42:34,000 let's put the five percent slopes into our balloy wick. 670 00:42:35,480 --> 00:42:38,519 What's the relationship between two percent slip and five is 671 00:42:38,559 --> 00:42:43,039 two and a half? If a two percent slope breaks 672 00:42:43,119 --> 00:42:46,880 one inch, a five percent slope will break two and 673 00:42:46,920 --> 00:42:52,000 a half inches for every foot. Because how MUDs will 674 00:42:52,079 --> 00:42:58,320 ten foot putt break twenty five inches? Right? How much 675 00:42:58,360 --> 00:43:01,719 will a five foot putt break twelve and a half inches? 676 00:43:01,840 --> 00:43:05,320 Five times two point five? All right? Now, let's to 677 00:43:05,320 --> 00:43:07,519 be done with all this by putting the six percent 678 00:43:07,559 --> 00:43:09,480 slopes in there, the ones we're not ever going to 679 00:43:09,519 --> 00:43:14,840 see right, it's three times as much. Two percent breaks 680 00:43:14,840 --> 00:43:17,920 one inch, six percent breaks three inches for every foot, 681 00:43:18,519 --> 00:43:21,679 thirty inches on ten feet and fifteen inches from five feet. 682 00:43:23,920 --> 00:43:26,440 Speaker 1: Okay, I think I think we got it. It's like 683 00:43:26,519 --> 00:43:29,320 we'll we're getting It's just like too much detail here, 684 00:43:29,360 --> 00:43:30,639 but I think we got your point. 685 00:43:30,800 --> 00:43:32,519 Speaker 3: Yeah, let me run let me run back through it 686 00:43:32,559 --> 00:43:32,960 real quick. 687 00:43:33,079 --> 00:43:33,360 Speaker 1: Okay. 688 00:43:33,360 --> 00:43:38,280 Speaker 3: We're bookwhacking the common putts that we can actually sink 689 00:43:38,519 --> 00:43:42,920 across flat green inside ten feet, and we want to 690 00:43:43,000 --> 00:43:46,880 know the different slopes and the green speeds, how they 691 00:43:46,960 --> 00:43:52,519 combine to generate specific information about how many inches it 692 00:43:52,639 --> 00:43:56,599 takes per foot you put ten feet on whatever it is, 693 00:43:56,599 --> 00:43:59,519 a twenty to thirty whatever it is, and however much 694 00:43:59,519 --> 00:44:02,320 it curls below the hole you measure that that's the 695 00:44:02,400 --> 00:44:05,159 answer for that stamp and slope combination. 696 00:44:05,519 --> 00:44:08,199 Speaker 1: And this will pull on your practice greens before you 697 00:44:08,239 --> 00:44:09,960 get out there. This is where you're trying to figure 698 00:44:09,960 --> 00:44:11,840 this out to take it with you out on the course. 699 00:44:12,360 --> 00:44:14,920 Speaker 3: And you don't even have to know the green speed, right, 700 00:44:15,800 --> 00:44:17,920 if you're going to play from the practice green onto 701 00:44:17,920 --> 00:44:20,280 the course that day, you don't even have to ask 702 00:44:20,480 --> 00:44:23,639 that question because the green speeds that day will be 703 00:44:23,679 --> 00:44:26,800 the same as the green on the practice green. So 704 00:44:27,000 --> 00:44:30,280 whatever it breaks on two percent slope, you can fill 705 00:44:30,320 --> 00:44:34,639 in all the details. If it happens to break ten inches, 706 00:44:35,039 --> 00:44:38,119 that will tell you that that is a stamp ten green, 707 00:44:38,400 --> 00:44:40,519 you can work backwards that way and figure that out. 708 00:44:43,480 --> 00:44:46,079 If if you know it's a stamp ten green and 709 00:44:46,159 --> 00:44:49,360 it breaks fifteen inches from ten feet, that tells just 710 00:44:49,400 --> 00:44:54,320 a three percent slope, you can work it that way. 711 00:44:54,840 --> 00:44:57,800 Speaker 1: I'm liking it, okay, yep. 712 00:44:58,000 --> 00:45:02,280 Speaker 3: So so basically I cre that and I'm proud of it. 713 00:45:03,800 --> 00:45:09,360 Speaker 1: We're proud of you too, Okay. And it's like we 714 00:45:09,440 --> 00:45:12,639 got our own Yale education here. Oh yeah, now, well 715 00:45:12,840 --> 00:45:15,159 we'll give a Stanford education here, a screw Yale. 716 00:45:15,239 --> 00:45:18,000 Speaker 3: Right, that's right. Let's do the last. Let's do the 717 00:45:18,079 --> 00:45:21,639 last little piece of reasonable, rough and rowdy Scotts. Okay, 718 00:45:23,039 --> 00:45:25,920 we didn't really read a putt on the green. We 719 00:45:26,000 --> 00:45:29,840 got a ballpark, right, right, got it. We got a 720 00:45:30,039 --> 00:45:34,639 generalized understanding that needs to be applied to a specific 721 00:45:34,719 --> 00:45:38,559 putt on the golf course. Okay, So when you get 722 00:45:38,559 --> 00:45:41,400 a put on the golf course, if it's flat, if 723 00:45:41,440 --> 00:45:45,000 it's two percent, if it's ten feet away. If it's 724 00:45:45,039 --> 00:45:47,639 a stint tin green the same as a practice green 725 00:45:47,719 --> 00:45:50,840 or whatever it is, then you're you're kind of ready 726 00:45:50,920 --> 00:45:55,440 to lock and load. But that that seldom is exactly 727 00:45:55,519 --> 00:45:59,559 what happens. It's not exactly a two percent slope, it's 728 00:45:59,719 --> 00:46:02,840 not exactly ten feet away. It may be a little 729 00:46:02,880 --> 00:46:07,320 different green speed. You know, it may not be exactly flat. 730 00:46:07,679 --> 00:46:09,559 Speaker 1: It can't be exact. 731 00:46:10,000 --> 00:46:13,440 Speaker 3: That's straight. However, the people that Yale don't know this 732 00:46:13,599 --> 00:46:18,239 part of it. The golfers have to go from the 733 00:46:18,480 --> 00:46:25,039 generalized paradigm from the book to this specific put and 734 00:46:25,119 --> 00:46:30,559 apply the book knowledge reasonably and intelligently and adjusted. That's 735 00:46:30,599 --> 00:46:34,679 the engineer thing. Have to adjust your book knowledge to 736 00:46:34,800 --> 00:46:39,480 the facts that you face in the specifics. And that 737 00:46:39,599 --> 00:46:44,800 means that you readily understand that you don't have the 738 00:46:44,920 --> 00:46:47,360 read just because you did this thing on practice green. 739 00:46:47,400 --> 00:46:50,639 What you have is you have a very close understanding 740 00:46:50,679 --> 00:46:53,480 of where you start, and then you have the task 741 00:46:53,559 --> 00:46:57,079 of making a very minor adjustment to make an executive 742 00:46:57,079 --> 00:47:01,400 decision on what to actually do for this put, and 743 00:47:01,519 --> 00:47:04,559 that will carry you miles and miles past your competitors 744 00:47:04,920 --> 00:47:05,840 in reading puts. 745 00:47:07,559 --> 00:47:15,800 Speaker 1: Yeah, and the whole bottom line here is going past 746 00:47:15,840 --> 00:47:17,360 your competitors. 747 00:47:17,639 --> 00:47:24,280 Speaker 3: Beat them like a drum beat, like a for the pulp. Yeah, 748 00:47:24,320 --> 00:47:26,960 GoF is pretty good to be a psaltary support, but 749 00:47:27,280 --> 00:47:29,920 it's not the it's not really the blood curtaining and 750 00:47:30,079 --> 00:47:32,119 thrill you get when you beat other people. 751 00:47:32,559 --> 00:47:36,000 Speaker 1: It's kind of true, although whether it's for money or not, 752 00:47:36,079 --> 00:47:39,079 it's just knowing. It's like my favorite is getting in 753 00:47:39,119 --> 00:47:43,679 somebody's head. But yeah, I'm always competing against myself. But boy, 754 00:47:43,719 --> 00:47:46,280 beating someone we were out there playing with is always. 755 00:47:46,199 --> 00:47:48,800 Speaker 3: Somebody see you make that birdie and they can't make it. 756 00:47:48,920 --> 00:47:55,159 Speaker 1: Yep, yep, Yeah, god, Jeff, that was that was awesome man, 757 00:47:55,679 --> 00:47:59,679 Thank you all right, man, my dog is done with you, 758 00:48:00,400 --> 00:48:04,440 so uh so leave the parking lot of McDonald's.
