The Standard Scratch (S.S.) is computed on the night by taking the average of all players out and adding 2 shots to this.
If a player does not play on the night
No Change to their H/C.
If a player fails to break S.S.
They receive one increment of their handicap back, irrespective of how many under standrard scratch they are. See table below for increments.
If a player equals S.S.
No Change to their H/C.
If a player breaks S.S.
They lose an increment for EACH shot better than S.S. and the increments are as the table below. so if S.S. on a night is 16 and a player off 6.5 shoots 20 then as then are 4 shots better than S.S. they loose 4 *.4 which is 1.6. This means their new Handicap is 6.5 - 1.6 = 4.9.
Handicap Range Increments 0 to 2.0-.2 / 2.1 to 4.0-.2 / 4.1 to 6.0-.3 / 6.1 to 8.0- .4 / 8.1 to 10.0-.5 10.1 to 12.0-.6 / 12.1 to 14 -.0.6
