Here are two graphics showing perhaps a five-foot putt. In the green graphic, the player is playing to a spot about 1" outside the hole and playing about 3.5" of break with a speed that rolls the ball about a 1 foot past the hole. In the red graphic, the player is playing to a spot about half a ball inside the right edge of the cup (about 1" of break) with a speed that rolls the ball about 4 feet past the hole. In both cases, you're aiming at a SPOT, a precise, no-size point. The triangles are about the same width as the effective capture speed of the hole given the speed, so yo
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
