![]() ![]() Putting is about feel and information processing. The break is greater for faster greens than for slower ones. Green speed has much the same effect as uphill and downhill putts. Obviously, downhill putts break much more than uphill putts. Down hill putts can break anywhere from eight to 10 times the PBD. If you like to die your putts into the hole, then you need to allow for about 2 to 4 times the PBD for steeper slopes.įor similar conditions, moderate uphill putts break as little as half the PBD. The above guidelines assume you’re following the Dave Pelz suggestion for leaving your missed putts 17 inches past the cup. Haney’s goal was to figure out if you could use plumb-bobbin to determine the true amount of the break.Īfter examining lots of examples and producing numerous charts, Haney concludes that for typical green speeds (9 on the Stimpmeter) and level putts (no uphill or downhill slope), the amount of break varies from slightly more that the PDB for gentle slopes to about 1-1/2 times the PBD for steeper slopes. The force of friction causes the ball to slow down. ![]() ![]() Both are considered in the computer model. When you first stroke a ball, it first slides and then rolls. It also takes into account the effect of friction on a putt. It takes into account varying speeds of greens, the distance of a putt, and the amount of slope (both sideways and up or down). Using PBD, Haney developed a computer model on plumb-bobbing. That value is an indicator of how much the ball will react around the hole. But for all other putts, plumb-bobbing produces a discrete value. On a level putt with no right or left break, the PBD is zero. The distance from that spot to the center of the hole, Haney explains, is the plumb-bob distance (PBD), a measure of slope and distance at the ball. If you plumb-bob correctly, you’ll notice that the putter makes a point either left or right of the hole on the putting surface. You could learn all you need to know about plumb-bobbing in the first 5 minutes of a golf lesson. If it’s in line with the putter, the hole is flat. If it appears on the left, the hole slopes right. If it appears to the right of the shaft, the hole slopes left. Without moving your head, look up at the hole. Next, using your dominant eye, line up the putter so that the shaft’s lowest point covers the ball. Holding the top of the grip lightly between your thumb and forefinger, extend your arm slightly. Let your body tilt with the green’s slope. Keep your eyes parallel to whatever slope exists on the portion of the green you’re standing on. Stand behind the ball so the hole, ball, and your dominant eye are aligned. Improve your putting and you’ll slice strokes off your golf handicap quickly.īefore we get into Haney’s findings, lets take a look at plumb-bobbing and how to do it correctly. Haney’s model suggests that there’s more to it than meets the eye and that with a little effort you can use it to help determine how much a putt breaks. But a computer model developed by Fredrick Haney, Ph.D., a few years ago, is changing the way golfers think about plumb-bobbing. The biggest knock against plumb-bobbing in golf is that it tells you how a putt breaks but not how much. The question is can it help you sink a putt. Plumb-bobbing in golf is an old-school technique for generating information that’s useful in putting. You don’t need a golf tip to tell you that. ![]() In other words, the better you are at reading greens, the more likely you are to sink a putt. ![]()
