An 18-hole Score Differential is calculated as follows and rounded to the nearest tenth, with .5 rounded upwards:
Note: The PCC adjustment ranges from -1.0 to +3.0 (see Rule 5.6 Playing Conditions Calculation). |
If a player submits a 9-hole score, an 18-hole Score Differential must be created by combining two 9-hole Score Differentials. A 9-hole Score Differential is calculated as follows using 50% of the playing conditions calculation (PCC) adjustment for the day: |
Notes:
|
An 18-hole Score Differential is then created by either:
Note: An uncombined 9-hole score will be discarded when it becomes older than the twentieth Score Differential in the scoring record.
When an adjusted gross score calculates lower than the Course Rating, this results in the Score Differential being a negative number. Where this occurs, rounding is made upward towards 0. For example:
