Playing Conditions Calculation (PCC) - World Handicap Index

The Course Rating System, which will continue to serve as the cornerstone of handicapping when the WHS is launched next season, measures the difficulty of a golf course under normal conditions. Scoring data that is needed for the Handicap System should be a reflection of how the golfer performed during relatively stable course circumstances.

However, a good score on a normal day may turn mediocre when the weather is challenging. In addition to the impact of Mother Nature, tough course setups such as unusual rough height or hole locations can have a significant impact.

When the World Handicap System launches in 2020, it will bring with it more responsiveness to these types of course scenarios with a new, exciting feature called the Playing Conditions Calculation – or PCC.

The PCC will be triggered when abnormal playing conditions cause scores to be unusually high or low on a given day. This calculation will adjust score differentials to better reflect the player’s actual, demonstrated performance (it will not change the official Course & Slope Rating).

Conservative in nature, the PCC will be an automated statistical procedure within the WHS, with special notations in the player’s scoring record. Details we know at this time are:

  • There must be at least eight scores submitted on the day of play for the adjustment to be made
  • The calculation will only consider scores of players at or below a Handicap Index of 36.0
  • Both 9- and 18-hole scores will be considered
  • The PCC will help with seasonality where courses play longer or shorter due to soft or hard / firm conditions
  • It will be imperative that players post scores immediately after play so the PCC will kick in when appropriate
