PCC Explained: Why Bad Weather Can Mean No Adjustment

A miserable day does not guarantee a PCC adjustment. The calculation compares eligible scoring performance with expectations; the result is not a weather rating.

Original fictional examples

17.0: Fictional adjusted gross 90, Course Rating 71.2, Slope 125, PCC 0.
113/125 ×(90−71.2−0) =16.9952, rounded 17.0.
Case 1
PCC +2: All other inputs held fixed.
113/125 ×(90−71.2−2) =15.1872 →15.2.
Case 2
PCC −1: All other inputs held fixed.
113/125 ×(90−71.2+1) =17.8992 →17.9.
Case 3
No forecast equation: The three PCC inputs are supplied teaching values.
No claim is made that a particular weather pattern generates any of them.
Case 4

The short version

Do not derive PCC from rain, wind or temperature alone.
Post promptly on the day of play for the scoring analysis.
PCC changes a differential; it does not rewrite actual strokes.

Read the sign inside the differential

The worked 18-hole equation subtracts PCC before applying 113/Slope. A positive PCC therefore reduces the differential for a fixed adjusted gross score. At Slope 125, changing PCC by two does not produce exactly a two-point differential change.

These numbers demonstrate arithmetic only. They do not recreate the proprietary statistical determination of the day’s PCC or predict an individual Index update.

Scoring data and weather tell different stories

The Rules describe an automatic statistical comparison using acceptable scores and minimum data requirements. At least eight qualifying scores are required for the stated daily calculation. A windy afternoon can still produce no adjustment if the scoring evidence does not support one.

A calm day can also involve course conditions affecting scores. Avoid treating a forecast, one unhappy group or a personal bad round as the statistical result for the entire course.

Post on the correct date and promptly

Prompt same-day submission helps the calculation use the eligible scoring evidence. A later entry should still use the correct played date and authorized workflow; do not change dates to seek a preferred adjustment.

The output feeds a Score Differential, not the ordinary competition card. For the best-eight record effect, read why an Index can rise. For nine-hole records, use their applicable combination method.
