Are you wondering how your Handicap Index on Handicap System Players Web App is calculated?
The golfer handicap index is calculated in Handicap System (online) not in Handicap System Players Web App. Here is a link to the method for calculating the handicap / index.
Please note: This often trips people up. It is the 10 best differentials of the 20 most recent scores not the 10 best scores themselves that drive the calculation.
