World Handicap System 2020:
Score Differential Calculation
Adjusted Gross Score
Playing Conditions Calculation (PCC)*
Score Differential (rounded to the nearest tenth) =
(113 / Slope Rating) * (Adjusted Gross Score – Course Rating
– PCC adjustment)
Score Differential = 113/125 * (94 – 73.0 – 0)
Score Differential = 19.0
Score Differential for a 9-hole score = (113 / 9-hole Slope Rating) * (9-hole Adjusted Gross Score - 9-hole Course Rating - (0.5 * PCC adjustment). A 9-hole Score Differential remains unrounded until combined with a second 9-hole Score Differential and an 18-hole Score Differential is calculated.
*Playing Conditions Calculation: Course Ratings are based on normal playing conditions, but the difficulty of a golf course can vary substantially from day to day due to course conditions, weather conditions and/or course set-up. The Playing Conditions Calculation (PCC) determines whether playing conditions on the day differed from normal conditions to the extent that an adjustment is needed to compensate. It is a daily statistical automatic calculation that compares the scores submitted by players on the day against expected scoring patterns.
