You may recall hearing Dave Pelz tell you that the optimal distance a putt has to roll past the hole is 17 inches. How big might you guess the hole is at 17 inches? 4 inches wide? 3 ½? What if I told you that the hole, at 17 inches, was only about 2¼ inches wide? What? Am I crazy? No - it's just math. Consider a well cut hole, and what's required for the putt to go in. For a putt to be holed, it has to have enough time for the ball - 1.68 inches in diameter - to fall half that distance, or 0.84 inches, or more. Gravity is a constant force (9.8 m/s 2 ) and 0.84 inches is a

http://www.dstgolf.com/optimise-golf-swing/how-dst-golf-clubs-work You'll notice that everything in that description talks about how the shaft appears, or how a line appears, so that you set up properly. In essence, everything - the shaft being bent, the wide sole with a specific bounce, and the line near the hosel - is geared toward one thing: to get the handle forward at setup. As you can see, I've done that here in two swings: So far so good, right? I added a white line so that you can see the curve in the shaft. I will tell you that it appears to b- 40 replies

Here's a thread where we can all speculate and share data and thoughts and discuss "theories" and hypotheses… I've shared parts of this in other topics, but I hope to collect everything here, while simultaneously simplifying my position (maybe? hopefully?). I'd previously written a post about how you should almost always leave the flagstick in when you're given the opportunity to (without penalty). It, when you're off the green, tends to help you far more often than it hurts. The flagstick typically slows the ball down and lets it fall into the hole or at least stay closer than it otherwi

This stuff really intrigues me.....there is more real science out there on the golf swing than you might think. I started another thread for an article on movement variance....and then I found this article.....and then some others. So I decided to start a catch-all thread. Moderators feel free to add the other article to this thread if you think it's necessary. Anyway, to start the ball rolling..... Here is a link to a paper by Bob Grober, PhD. Bob is an adjunct at Yale's department of applied physics. He has done a lot of study on tempo in the golf swing, and even sold a
