Abstract

The method generally involves obtaining data for the golfer's typical playing characteristics using a plurality of golf clubs, determining an average end location for each of a plurality of shots taken with each of a plurality of golf clubs, and calculating the distance from the end location of each of the plurality of shots taken with each of the plurality of clubs to a target location, each distance being a putt distance.

Claims (26)

1. A method comprising:

obtaining a downrange dataset comprising a series of shots from a test of a golf club in a golf club set;

developing a target for the downrange dataset;

calculating a distance of every shot within the downrange dataset to the target;

recording the distance as a putt distance;

predicting an average number of strokes from each shot to the target;

averaging the average number of strokes to determine the average strokes for each club in the golf club set;

averaging the average strokes for each club across the set of clubs to determine a set average;

multiplying the set average by eighteen to determine an average strokes per round.

2. The method according to claim 1 , wherein the target is calculated using an average end location of all shots in the dataset.

3. The method according to claim 1 , wherein the target is a hole location.

4. The method according to claim 1 , wherein the step of averaging the average strokes for each club across a set of clubs to determine a set average is performed using a weighted average.

5. The method according to claim 1 , wherein the step of averaging the average strokes for each club across a set of clubs to determine a set average is performed using a standard average.

6. The method according to claim 1 , further comprising comparing the average strokes per round from the golf club set with an average strokes per round from another golf club set to determine a potential benefit of strokes saved.

7. A method of selecting a golf club to lower a golfer's score, the method comprising:

having the golfer take a plurality of putting shots towards at least one golf course hole using a plurality of combinations of golf clubs;

calculating a putt distance at the end of each shot;

averaging the putt distance from the shots for each golf club;

simulating a round using the averaged putt distance for each combination of golf clubs;

calculating a score based upon the averaged putt distance for each of the combination of golf clubs; and

providing the golfer with the combination of golf clubs having the lowest score.

8. The method according to claim 7 , further comprising identifying a golf club combination having a lowest risk of missing a shot.

9. The method according to claim 7 , wherein the step of having the golfer take a plurality of putting shots using a plurality of combinations of golf clubs further includes having the golfer take said plurality of shots at a plurality of locations on a golf course.

10. The method according to claim 9 , wherein the step of calculating a score for each combination of golf clubs further comprises calculating a lowest average score at each of the plurality of locations on the golf course.

11. The method according to claim 7 , wherein the plurality of golf club combinations is composed of three club combinations.

12. The method of claim 11 , wherein each of the three club combinations has a predictive score and an assigned risk, and wherein the assigned risk is calculated using the standard deviation of predicted scores from the combination of clubs.
