Please be aware that from 01/04/2024 the main changes with Course and Playing Handicaps are as follows:
Course Handicap Calculation
- Old
- HI * (SR / 113)
- And round it
- New
- HI * (SR / 113) + (CR - PAR)
- And round it
Competition Playing Handicap Calculation
- Old
- HI * (SR / 113)
- And round it
- Then multiply by the Competition Handicap Allowance: eg 95% / 85%
- And round it again
- New
- HI * (SR / 113) + (CR - PAR)
- Then multiply by the Competition Handicap Allowance: eg 95% / 85%
- And round it
Mixed Tee Competition Score Balancing
- Old - For Medal, Stableford and ParBogey the difference between the Course Ratings of each Tee in use
- New
- Medal the difference between the PAR of each Tee in use
- Stableford and Par/Bogey no longer need Score Balancing as CR - PAR automatically balances the PH's
- Scratch Medal continues to use the difference in the Course Ratings
Matchplay
Individual Matchplay
- The full difference between the rounded Course Handicaps
Pairs Better Ball Match Play
- 90% of the difference between the rounded Course Handicaps
Foursomes Matchplay
- 50% of the difference between the combined rounded Course Handicaps
Greensomes Matchplay
- The difference between 60% of the Low CH & 40% of the High CH of each pair
- PLEASE NOTE - MACHINE PRECISION COURSE HANDICAPS ARE USED
Matchplay Score Balancing
- The difference the PAR of each Tee in use
Examples of rounding confusion
SR = 138 : CR = 70 : PAR = 70
For Individual Medal / Stableford / Par-Bogey at 95%
- 11.6 = CH: 14.1663717 (14) & PH: 13.4580531 (13)
- 11.7 = CH: 14.2884956 (14) & PH: 13.5740708 (14)
- 11.8 = CH: 14.4106195 (14) & PH: 13.6900885 (14)
- 11.9 = CH: 14.5327434 (15) & PH: 13.8061062 (14)
In summary we can see that HI's 11.6 and 11.9 return a PH that is 1 shot lower than the CH which is what your players were used to pre 01/04/2024
However HI's of 11.7 & 11.8 return a CH of 14 and a PH of 14 which has been the cause of most of the confusion
Is there an easy way to calculate a PH?
Yes, use the following method to avoid any confusion with BODMAS when working out a PH on a calculator or your phone
Slope Rating / 113: eg (138 / 113) = 1.22123894
1.22123894 multiplied by the HI: eg (1.22123894 * 11.7) = 14.2884956
14.2884956 plus the CR: eg (14.2884956 + 70) = 84.2884956
84.2884956 minus the PAR: eg (84.2884956 - 70) = 14.2884956
14.2884956 multiply by Competition Allowance: eg (14.2884956 * 0.95) = 13.57407082
13.57407082 Round to the PH of 14:
