![]() To determine this speed, the golfer needs to consider the rolling friction between the ball and grass, the vertical displacement of the hole relative to the ball, and the distance the ball must travel to reach the hole. First, the golfer must determine the club head speed required to displace the ball from its resting position to the hole. A golfer s putting performance is dependent upon three skills. However, handicap only accounted for approximately one-quarter of the variation in putting performance. Carnahan (2002) demonstrated that handicap was a statistically significant explanatory variable of putting performance. Putting performance is linked to handicap, but the exact form of the relationship is unclear. Hence, a golfer s putting performance plays a large role in the overall score. Introduction According to the Professional Golf Association (PGA) Tour statistics listed on the PGA web site, the putting stroke accounted for approximately 41% of all strokes made during the average tournament round of golf in 2002 (PGA, 2002a,b). Keywords: balance, golf, physical model, putting. The plumb-bob method was found to be an invalid system for determining the break of a putt. A error on a 1.4 m (* 4.5 ft) putt translates into reading an extra 0.08 m of break and a missed putt. Half of the participants in the study deviated by or greater from standing perpendicular to a slope. ![]() The second experiment examined the ability of a golfer to stand perpendicular to a slope. It was determined that if the slope of the green beneath the golfer was different from the slope between the ball and the hole, then the plumb-bob method would provide an incorrect indication of break. ![]() ![]() In the first experiment, a controlled putting environment was constructed to assess the plumb-bob method in determining the break of a putt, if the slope of the green was not constant from the position of the golfer behind the ball through to the hole. Two separate experiments were conducted to examine the consequence of violating inherent assumptions in the method. SPRIGINGS* College of Kinesiology, University of Saskatchewan, Saskatoon, SK S7N 5C2, Canada This study evaluated the validity of the plumb-bob method as used to determine the break of a putt. The flaw in the theroy of plum bobbing telling you how far to play the ball outside the cup comes when you factor in speed, it tells you nothing about speed and that changes the break.so it can be a tool if you are just having a hard time seeing the break.but other than that, I just don't use it.1 Journal of Sports Sciences, 2005, 23, Evaluation of the plumb-bob method for reading greens in putting SASHO J. Just close the non dominant eye like you were going to shoot a gun.hold the putter in your fully outstretched arm in your finger tips freely enough so the weight of the head will allow it to naturally swing to ace the bottom part of the shaft over the ball or marker and if there is a break in the putt, the cup will be on one side of the top of the shaft or other.Īs I said earlier.I am a decent putter.and I don't plum bob.unless there is a very subtle break that I just cant decide if it's straight or goes one way or the other slightly.then I might throw a quick plum bob in there just to see the direction of the break. You do not need to start with both eyes open and then close the non dominant eye to "move the cup" Okay, I think some are getting confused with the explanation of how to find your dominant eye and the explanation of plum bobbing.
