9-Hole Scores
When a player posts a 9-hole score played on a rated nine, a 9-hole Score Differential will be calculated for the 9 holes played, and that value will be combined with an expected score based on the player’s Handicap Index to create an 18-hole Score Differential. The expected score is based on the average Score Differential of a player with a given Handicap Index and a normal distribution of scores – so it is not specific to each player.
For players who are posting initial scores to establish a Handicap Index, expected score will not apply until they play and post scores from 54 holes. Once the player has posted scores from 54 holes and an expected score can be determined for the player, an 18-hole Score Differential will be calculated for each 9-hole score and displayed within their scoring record. At this time the player will have established their initial Handicap Index.
