The below are the steps taken when calculating the handicap within the site.

Step 1
First adjust your total shots for each hole so they are a maximum of 2 shots over for each hole, so if you got a 7 on a par 4, adjust the score to a 6.

Step 2
Add all your holes together and minus this from the course SSS of the tee type you were playing. e.g. I scored 85 in total on a yellow tee SSS of 70 , 85-70=15

Step 3
Take your playing handicap away from your total worked out in step 2. Your playing handicap is you’re rounded up/down value of your handicap. e.g. if your handicap is 17.1 you played of 17, if your handicap is 17.8 you played of 18. The calculation for this step is 17-15=2

Step 4
For every 1 under your handicap you get a 'Category Shot' taken of. Your Category Shot varies depending on your current handicap, the break downs are listed in the table below. Example for a 17.1 handicap they are category 3 so they get 0.3 per 1 shot under par. The calculation for step is 2*0.3=0.6. Carry on to step 5.

If the result from step 3 is over par then you will add 0.1 onto your handicap and that will be the end of the handicap adjustment.

Step 5
You will be at this step if you were under par on step 3. You will now need to take the result of step 4 off your actual handicap. The calculation for this step is 17.1-0.6 = 16.5

Handicap of player	Buffer Zone	Nett Differentials below zero	Nett Differentials above buffer zone
Category 1: Handicaps up to 5	0 to +1	Handicap reduced by 0.1 for each stroke Nett Differential is below zero	Handicap increased by 0.1
Category 2: Handicaps 6 to 12	0 to +2	Handicap reduced by 0.2 for each stroke Nett Differential is below zero	Handicap increased by 0.1
Category 3: Handicaps 13 to 20	0 to +3	Handicap reduced by 0.3 for each stroke Nett Differential is below zero	Handicap increased by 0.1
Category 4: Handicaps 21 to 28	0 to +4	Handicap reduced by 0.4 for each stroke Nett Differential is below zero	Handicap increased by 0.1
Category 5: Handicaps 29 to 36 (*)	0 to +5	Handicap reduced by 0.5 for each stroke Nett Differential is below zero	Handicap increased by 0.1
