In November of 2020 the Handicap System will change Worldwide.
Here is a little forerunner of how it works in relation to Whetstone Golf Club.
More About Handicaps
It’s relatively simple to use the handicap system to record and enter your scores, but for those with an interest in how it all works, read on.
First a few facts-
HANDICAP INDEX . This is your “HANDICAP” and is calculated to one decimal place.
A player’s COURSE HANDICAP is the number of strokes received prior to the adjustment of the STROKE ALLOWANCE and will be different for different courses
A player’s PLAYING HANDICAP is the strokes received after application of the
STROKE ALLOWANCE and calculated to the nearest stroke (.5 is rounded upwards).
E.g. 12.5 becomes 13. This represents the strokes received in a competition and will be different for different competition formats.
All courses have been allocated a COURSE RATING. (CR) This represents the difficulty of the course and is the expected score that a scratch golfer will make.
The SLOPE INDEX (SI) is derived from the expected difference in scores of a typical “Bogey” golfer from a scratch player. The SLOPE index is used to calculate the
An ACCEPTABLE SCORE is a score from a round that complies with all the requirements of the R&A “Rules of Handicapping” and is therefore processed through the handicap system.
ADJUSTED GROSS SCORE (AGS):- For the purposes of handicapping only, a player’s
score in a competition is adjusted by a “stableford reduction”. That is, all net scores on a hole worse than two over par are reduced to two over. This applies also to holes which have not been completed (NRs).
The PLAYING CONDITIONS CALCULATION (PCC) is an adjustment to your score to reflect the weather and course conditions. This only applies to handicap adjustment not to a competition result.
A player’s SCORE DIFFERENTIAL is the difference between a player’s ADJUSTED GROSS SCORE and the COURSE RATING, after correction for the SLOPE INDEX and the PCC.
The STROKE ALLOWANCE is a multiplication factor applied to the COURSE HANDICAP this depends on the Conditions or format of the competition. (E.g. 0.9 0.75 or 1 (Full)).
Note STROKE ALLOWANCE does not affect the adjustment of your handicap
Then when you play a round this is what happens:-
a) In the clubhouse or on the first tee there is a table of COURSE HANDICAP. Look up
the correct COURSE HANDICAP according to your HANDICAP INDEX.
b) If you are playing in a competition, you may need to apply the STROKE ALLOWANCE to get your PLAYING HANDICAP = COURSE HANDICAP x STROKE ALLOWANCE
c) When you enter your scores this is what the computer will calculate:-
Calculate the ADJUSTED GROSS SCORE.
Calculate the SCORE DIFFERENTIAL=(113/SR) x (AGS-CR-PCC)
The new HANDICAP INDEX is then recalculated as the average of the best 8 of the last 20 SCORE DIFFERENTIALS . If you haven't got 20 scores in your record then a sliding scale will be applied until you reach the required 20.
Example: A player with HANDICAP INDEX 14.7 scores 89 (after stableford reduction) off the White Tees (course rating 70.4/ Slope 123) when the PCC for the day is 1.
Then in a competition:-
with STROKE ALLOWANCE 0.95, the player receives:-
16(from the table below) x 0.95=14.9 (rounded to 15).
His net score for the competition is therefore 89-15=74
For handicap purposes:-
the SCORE DIFFERENTIAL = (113/123)*(89-70.4-1) = 16.2 (rounded to 16).
The HANDICAP INDEX is the best 8 of these from your last 20 rounds.
Simple isn’t it?
But just remember all you have to do is find your PLAYING HANDICAP and enter your scores.
The computer does all the rest!
But if you really, really get stuck then contact the Handicap Secretary
