Playing Conditions Calculation (PCC) – Updated August 2022

Update on the Playing Conditions Calculation (PCC) August 2022

At the end of each day, the playing conditions calculation takes place automatically to determine if scores made at the course were significantly higher or lower than the expected scores of the players who made them, primarily due to weather and/or course set up.

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.

The PCC:

  • Uses scoring data so no action is required by the club/course staff or golfer (except for posting scores),
  • Includes only scores made by players with a Handicap Index® of 36.0 or below,
  • Considers both 9-hole and 18-hole scores in the calculation, and
  • Only takes place if at least 8 scores were posted on a given day.
  • (Rule 5.6, Rules of Handicapping)

Since the launch of the World Handicap System in November 2020, England Golf has received feedback from golfers, clubs and counties on a wide range of topics.

One of the most talked about aspects of WHS has been the Playing Conditions Calculation (PCC) and its lack of movement compared to the old Competition Scratch Score (CSS).

England Golf have been analysing this very carefully across GB&I and have presented this to The R&A to help with their own research and that of other countries on this topic. As a result of this work, we can report that a change will be made to the algorithm that calculates PCC.

Statement from The R&A/USGA

Analysis of scoring data provided from 24 countries around the world indicates that a change to the rounding method used within the current PCC algorithm would increase the instance of an adjustment for abnormal conditions by an average of 5%.

For example, in countries where an adjustment for PCC only occurs on average 10% of the time on eligible days, this change will increase the average to about 15%.

This small change, recently approved by the Handicap Operations Committee, is in response to feedback from national associations that the current PCC algorithm is too conservative.

While this may feel like a small change, we expect the impact to be significant in highlighting days where a player’s performance was significantly different from that expected by the system.

Please note that there will be no change to the visibility of the calculation. This is an algorithm built within the WHS and is not available to clubs.

This change will not be made retrospectively and will take place on or around Monday 22 August 2022.

Playing Conditions Calculation (PCC)

Abnormal playing conditions can be caused by weather and or course set-up

The PCC assesses whether playing conditions on the day were ‘normal’ or significantly harder or easier than normal.

    • When abnormal playing conditions cause scores to be higher or lower than expected on a given day, a Playing Conditions Calculation will adjust score differentials to better reflect the player’s actual performance
    • This means that a higher score on a difficult day may still be a good score and one of the player’s best 8, and used to calculate their updated Handicap Index

Application of the PCC

    • It is performed only once for a day
    • Considers all acceptable scores submitted on a golf course (all formats, competitive and recreational, 9- and 18-holes)
    • Requires at least eight acceptable scores submitted by players with a Handicap Index of 36 or below
    • Is automatically applied within the calculation of Score Differentials for all players.
    • Is designed to be simple and conservative in nature, adjusting score differentials in integer values ranging from -1 to +3
