Step 6: Apply Section 10-3 for players with two or more eligible tournament scores.


10-3. Reduction of Handicap Index Based on Exceptional Tournament Scores

Using the definition of a tournament score (see tournament score and Decisions 10-3/1 through 10-3/6), the Committee (preferably the Handicap Committee in consultation with the Committee in charge of the competition) must determine in advance whether a score is to be designated as a tournament score that is to be identified by the letter “T” when posted (e.g., 82T). These scores are often referred to as “T-Scores” as in Section 10-3c.

 a. Procedure

The following procedure must be used as an alternate calculation of a Handicap Index for players with two or more eligible T-Scores. A player’s Handicap Index may be reduced under this procedure when a player has a minimum of two eligible T-Score Handicap Differentials that are at least 3.0 better than the player’s Handicap Index calculated under Section 10-2.

The Handicap Committee or handicap computation service must apply the following steps to determine if there is a reduction in Handicap Index calculated under Section 10-2.

 b. Steps

Example: A player with a Handicap Index of 17.3 has three eligible T-Scores, an 82T, 83T and 85T. Two of these eligible T-Scores, an 82T and 83T, produce the lowest T-Score Handicap Differentials. They were made on a course with a USGA Course Rating of 70.6 and a Slope Rating of 130.

Step 1: Calculate T-Score Handicap Differentials by subtracting the USGA Course Rating from each eligible T-Score; multiply the result by 113, and divide by the Slope Rating for each course played. Select the two lowest eligible T-Score Handicap Differentials.

Step 2: Subtract the second lowest T-Score Handicap Differential from the Handicap Index under Section 10-2. Continue with the next step if the result is 3.0 or greater.


Step 3: Average the two lowest T-Score Handicap Differentials.


Step 4: Subtract that average from the player’s Handicap Index.


Step 5: Using the number (rounded to the nearest tenths place (7.0) from step 4 and the total number of T-Score in the player’s record (3), use the Handicap Reduction Table to determine the amount the player’s Handicap Index is to be reduced.

Step 6: Subtract the table value from the player’s Handicap Index. The result of that subtraction will be the player’s reduced Handicap Index, provided that it is at least 1.0 less than the Handicap Index based on the formula in Section 10-2. The reduced Handicap Index is to be identified with the letter R when displayed in handicap reports or on the computer screen (e.g., 12.3R).



Example :

Value from Handicap Reduction Table 5.0

Handicap Index — Table Value: 17.3 – 5.0 = 12.3

Reduced Handicap Index: 12.3R

 c. Counting Tournament Scores

(i) T-Score Counter — The number of eligible T-Scores will be counted on a revolving 12-month basis. In order to keep track of the counter, but not save every T-Score, a counter for each month is needed. The T-Score counter will contain the sum of the latest 12 monthly counters plus any T-Scores older than one year that are a part of the 20 score history. The monthly counter will increase based on the date a score is processed, not the date of the score.

(ii) Best T-Score File — Up to the best six eligible T-Scores are saved in a “Best T-Score File,” separate from the player’s scoring record of the most recent 20 scores.

(iii) Adding T-Score — When a new T-Score is posted, it becomes part of the player’s normal scoring record as a score and Handicap Differential. If the “Best T-Score File” has fewer than six eligible T-Scores, the new T-Score is added to that file. If the file already has six T-Scores, the new T-Score, if better than any T-Score in the file, is added to the file and the worst T-Score in the file is deleted from the file, regardless of the date of the T-Score.

(iv) Discarding Old T-Scores — At each handicap revision, each T-Score in the “Best T-Score File” is checked to see if the score is older than one year and no longer part of the player’s current 20 score history. If so, the score is deleted from the file. Deleted T-Scores are replaced by the best eligible T-Scores (if any) in the player’s scoring record that are not already in the “Best T-Score File.” 

 d. Duration and Variation of Reduction

Handicap Index reduction for exceptional T-Scores is calculated at each handicap revision and may vary from revision to revision based on a number of factors. These factors may include the following:

• Additional T-Scores;

• Expiration of eligible T-Scores;

• Variation in 10-2 calculation;

• Fluctuation of 10-2 calculation in relation to the two lowest eligible T-Scores

 e. Handicap Committee Review of Reduction

The Handicap Committee must review all reductions. As a result of review, the Handicap Committee may:

• Continue to allow the reduction to run its normal course, as described in Section 10-3d, or

• Further reduce the Handicap Index. For example, the Committee may conclude that the player’s performance continues to be better than the potential ability indicated by the 10-3 reduction. In that case, the Committee replaces the reduced Handicap Index with an even lower modified Handicap Index, continuing to review the reduction after each revision period (See Section 8-4e), or

• Override the reduction. For example, the Committee may cancel the reduction to a Handicap Index for a player who has been injured and whose reduction was based on T-Scores prior to the injury. In that case, the reduction is inconsistent with the player’s scoring record. The Committee replaces the reduced Handicap Index with the Handicap Index calculated under 10-2 and ceases designating it with an R. The Committee will have the option to continue to override after each revision period for as long as at least two exceptional T-Scores continue to trigger a Section 10-3 reduction. Once the player’s scoring recordcontains fewer than two exceptional T-Scores, the Committee must cease overriding and rely on the normal calculation under Section 10-2.

• Decrease the amount of the reduction. The Committee may decide that the player’s full 10-3 reduction does not reflect the player’s potential ability, but a reduction is still necessary. In this case, the Committee may modify the amount of the reduction and the player’s Handicap Index as calculated by Section 10-2. For example, if the player’s 10-3 calculation is a 10.0R, but the 10-2 calculation is 15.0, the Committee could change the player’s reduced value to a value of 12.5M. This does not completely override the player’s reduction.
