BRIEF SUMMARY OF THE INVENTION
The present invention is a method for fitting a golf club for a golfer based on the golfer's ball striking characteristics. 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. The method further comprises using the putt distance to determine an amount of stokes necessary to reach the target location from the end location for each of the plurality of shots taken with each of the plurality of golf clubs. An average amount of strokes value is calculated for each of the plurality of golf clubs. The average amount of strokes value is standardized to determine a set average. The set average is then multiplied by eighteen which gives an average strokes per round saved value.
This method can be used to automate a player's selection of golf clubs for the set they build and can also be used to develop devices to suggest potential golf clubs for player's based on historical distributions stored on that device.
Having briefly described the present invention, the above and further objects, features and advantages thereof will be recognized by those skilled in the pertinent art from the following detailed description of the invention when taken in conjunction with the accompanying drawings.



BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
FIG. 1 is a flow chart of a preferred method of the present invention.



DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, a method for fitting a golf club to a golfer based on the golfer's ball striking characteristics is provided 100. The method comprises obtaining data for a golfer's typical playing characteristics using a plurality of golf clubs 101. An average end location for each of a plurality of shots taken with each of the plurality of golf clubs is determined 102. The distance from the end location of each of the plurality of shots taken with each of the plurality of golf clubs is calculated, and termed the putt distance 103. The putt distance is used to determine the amount of strokes necessary to reach the target location from the end location for each of the plurality of shots taken with each of the plurality of golf clubs 104. An average amount of strokes value for each of the plurality of golf clubs is calculated 105. The average amount of strokes value is standardized to determine a set average 106. The set average is then multiplied by eighteen to obtain an average stroke per round saved value 107. Preferably, the target location is the location of the hole. The strokes per round saved value can be compared from one set to another set to determine the potential benefit of strokes saved. The set average can be multiplied by eighteen because one of the clubs within the defined set will be used as an approach to the target location. Additionally, the method may further comprise using the average amount of strokes value for each of the plurality of golf clubs to provide the golfer with a plurality of suggested clubs based on a club selection that would give a lowest average score for the hole.
In one embodiment, the method further comprises wherein the plurality of suggested clubs comprises three options that would give the three lowest average scores for the hole at each location. In another embodiment, the method comprises wherein the golfer can compare the lowest average score for a particular course with another golfer's lowest average score for the same course. In yet another embodiment, the method comprises wherein the golfer can compare the lowest average score for a particular hole with another golfer's lowest average score for the same hole. Further, the method may comprise wherein the golfer is given a predictive score based on use each option of the plurality of suggested clubs. Also, the method preferably comprises wherein the golfer is given an assigned risk associated with each option of the plurality of suggested clubs.
The method comprises taking a downrange dataset from a test of a given golf club as the input dataset. A target is developed for that particular set of data. The target is calculated using the average end location of all shots. The target is preferably the holes location. The distance of every shot is calculated within the downrange data set to the target and recorded as a putt distance. With each putt distance, the method predicts an average amount of strokes from each shot to the target. The average amount of strokes for all shots is averaged to determine the average strokes for each club. The average strokes for each club is averaged across a set of clubs with either a weighted or standard average to determine the set average. The set average is multiplied by 18 to determine an average strokes per round. The strokes per round can be compared from one set to another set to determine the potential benefit of the strokes saved.
The method of determining club selection based upon lowering the golfer's score is used as a course assistant to determine the lowest possible score for the golfer. The method putt distance at the end of each shot and the average for each club stored is sued to determine the golfer's club selection at each location on the golf course that reduces the risk on each shot. The information is used to simulate a round using player data and for each combination of predicted clubs, a score for each hole can be determined. The club selection with the lowest average score for the hole can be given to the player. The lowest average score at each location can be recalculated at each hole. A choice of three club combination selections can be given at the start of the hole with a predictive score and the assigned risk of each choice at the start of the hole, which allows the golfer to select the risk and reward of each club combination. The risk is calculated using the standard deviation of the predicted scores from the combination of clubs within the prediction. Further, a collective group of golfers can use the strokes saves in the rating of golf courses using a representative golfer population to calculate the average scores and rate course against course or hole against hole.
From the foregoing it is believed that those skilled in the pertinent art will recognize the meritorious advancement of this invention and will readily understand that while the present invention has been described in association with a preferred embodiment thereof, and other embodiments illustrated in the accompanying drawings, numerous changes, modifications and substitutions of equivalents may be made therein without departing from the spirit and scope of this invention which is intended to be unlimited by the foregoing except as may appear in the following appended claims. Therefore, the embodiments of the invention in which an exclusive property or privilege is claimed are defined in the following appended claims.
