Adjusted Gross Score

What is Adjusted Gross Score for?

Adjusted Gross Score is calculated after each round in WHS system. Rules of Handicapping state that “A score for handicap purposes should not be overly influenced by one or two bad hole scores, which are not reflective of a player’s demonstrated ability.” So, for handicap purposes, the number of strokes scored on each hole is adjusted as following:

  • the maximum hole score is limited to net double bogey on each played hole
  • for adjustment purposes the maximum Course Handicap is limited to 54
  • if number of strokes on a hole exceeds net double bogey the score is adjusted to net double bogey
  • if a player starts the hole but does not hole out the score is set as net double bogey

Net Double Bogey is calculated using the following formula:

adjusted gross score - net double bogey

When a player submits the score before his first (initial) Handicap Index is obtained there is no net double bogey value. Then the limit of par+5 is used for above adjustment of score on each played hole. Therefore the Course Handicap for an 18-hole round is 54 and that for a 9-hole round is 27.

The value of Course Handicap is needed for Adjusted Gross Score calculation.

The difference between the CONGU countries (UK and Ireland) and other countries (Rest of the World ) is the approach to a par-based adjustment (Course Rating minus Par) in the calculation of the Course Handicap. CONGU countries do not apply this adjustment, while other countries use the CR and par values in the formula.
