USGA HANDICAP INDEX CALCULATION

You have 20 scores available. Each score produces a differential which is calculated as follows: (Score - Rating) x 113 / Slope.

Based on your available scores, the following table will determine the score differentials to be used in calculating your Official USGA handicap Index.

Differentials To Use Table

Scores Available	Differential(s) to Use
20	Lowest 10
19	Lowest 9
18	Lowest 8
17	Lowest 7
15 or 16	Lowest 6
13 or 14	Lowest 5
11 or 12	Lowest 4
9 or 10	Lowest 3
7 or 8	Lowest 2
5 or 6	Lowest 1

Lowest 10 Differential(s)

Used	Score	Type	Date	Rating/Slope	Differential
*	90	T	14-8	70.4/125	17.7
*	84	T	14-6	68.7/125	13.8
*	86	T	14-5	68.5/128	15.4
*	82	T	14-4	68.6/122	12.4
*	90	T	13-9	69.8/124	18.4
*	92	T	13-9	69.9/128	19.5
*	89	T	13-9	68.8/125	18.3
*	90	T	13-7	70.9/123	17.5
*	86	T	13-5	70.1/126	14.3
*	87	T	13-5	69.6/124	15.9

Official USGA Handicap Index is calculated as follows.
	Differentials to Use for 20 Scores	10
	Sum of 10 lowest differentials	163.2
	Average based on 10 lowest differentials	16.3
	Average multiplied by .96 (Bonus for Excellence)	15.667
	Delete all digits after tenths	15.6
	Official USGA Handicap Index	15.6

TOURNAMENT REDUCTION 'R' CALCULATION

This calculation uses all the tournament scores played within the last 12 months or within your last 20-score history regardless of date played. These are called eligible tournament scores and there must be at least 2 eligible tournament scores to continue this calculation.

Your record contains 20 eligible tournament scores. The 2 tournament scores that produced the lowest differentials are listed below. These 2 lowest differentials are used to start the alternative calculation.

Lowest 2 Eligible Tournament Scores

Used	Score	Type	Date	Rating/Slope	Differential
*	84	T	14-6	68.7/125	13.8
*	82	T	14-4	68.6/122	12.4

Official USGA 'R' Handicap Index is calculated as follows.
	Lowest Eligible Tournament Differential	12.4
	Second Lowest Eligible Tournament Differential	13.8
	The second lowest differential is subtracted from the Official USGA Handicap Index	15.6 - 13.8 = 1.8
Since 1.8 is less than 3.0 the index is not subject to T-Reduction.
