Legacy Golf Tour utilizes customized handicap system software with tournament proven adjustment factors to prevent sandbagging. The tour proprietary system is similar to the standard USGA format but is modified to, in our view, more accurately reflect current potential of players based on more recent tournament score histories.


How are USGA handicap indexes calculated?

This is a brief overview of how USGA handicap indexes are calculated. The "Reduction of Handicap Index for Exceptional Tournament Performance" is not discussed. For complete information about USGA handicapping refer to the "USGA Handicap System Manual". This manual can be ordered from the USGA (908-234-2300) or visit their website at www.usga.org.

Step 1

The first step is to enter only a golfer's adjusted gross scores (not gross scores). To adjust an original gross score you use the Equitable Stroke Control (ESC). ESC is used to downwardly adjust individual hole scores for handicapping purposes in order to create handicaps that better represent a golfer's playing ability. ESC prescribes a maximum number of strokes that can be entered for any hole. This maximum is based on the golfer's Course Handicap and is obtained from the table shown below.

18 hole handicapping
Course Handicap
Limit on any hole
9 or less
Double bogey
10 through 19
20 through 29
30 through 39
40 and above
9 hole handicapping
Course Handicap
Limit on any hole
4 or less
Double bogey
10 through 19
10 through 14
15 through 19
20 or more

Maximum strokes per hole are allowed according to the player's course handicap. If a golfer does not yet have an index, the maximum allowed index will be used. (36.4 / 18.2 for men, 40.4 / 20.2 for women--for 18 \ 9 hole handicaps).

Step 2

The second step in computing a Handicap Index is to compute a Handicap Differential for each score that is to be considered in the Handicap Index calculation. The Handicap Differential is computed using the following formula:

Handicap Differential = (Adjusted Gross Score - Course Rating) X 113 / Slope Ratingg

(113 is the Base Slope, or the Slope Rating of a course of standard difficulty according to the USGA.)

If your adjusted gross score is more than the Course Rating for the course on which the round was played, the Handicap Differential will be a positive number. If your adjusted gross score is lower than the Course Rating, the Handicap Differential will be negative.

Step 3

The third step in calculating your Handicap Index is to select the lowest Handicap Differentials. The following table is used when selecting the best, or lowest, Handicap Differentials. If more than 20 scores have been entered, the 10 best differentials of the 20 most recent scores are used for the calculation.

Step 4

The fourth step in computing the Handicap Index is to calculate the average of the selected lowest Handicap Differentials. Simply add the selected Handicap Differentials together and divide by the number of selected Handicap Differentials.

Step 5

The fifth step in calculating the Handicap Index is to compute the net Handicap Differential average. For the USGA System the percentage by which the Handicap Differential averages are multiplied is 96%.

Step 6

Step six in computing the Handicap Index is to delete the digits after the tenths place of the net Handicap Differential average. Do NOT round off to the nearest tenths place. As established by the USGA, the default maximum Handicap Index on an 18-hole course is 36.4 for males and 40.4 for females. On a nine-hole course the default maximum Handicap Index is 18.2 for males and 20.2 for females. The maximum ceiling can be increased.
