What is a PCC?

Playing Conditions Calculation, or PCC, is a daily statistical calculation that determines if Score Differentials derived on a particular day differed from those associated with normal playing conditions to the extent that they significantly affected players’ performance. There may be multiple reasons for the deviation, but ultimately this is solely a statistical calculation. The PCC procedure compares the scores submitted by players on the day against expected scoring patterns. The procedure only takes place if at least 8 scores are posted on that day and only includes scores made by players with a Handicap Index of 36.0 or below. 


If scores were abnormally low or high, a PCC adjustment between -1 and +3 will be applied in the calculation of Score Differentials™ of everyone who played that day. A negative (-) adjustment means the course played easier than expected and a positive (+) adjustment means the course played more difficult than expected. A PCC of 0 means the course played as expected, which will be the case on most days.
