9 Hole Scaling Up using Expected Score

9 Hole Scaling Up using Expected Score

For a 9 hole score to be posted to a player's record, the WHS system requires it to be converted to an 18 hole score differential. This calculation uses your actual score for the 9 holes played, then scales it up to an 18 hole differential using a back 9 of standard playing difficulty, and an Expected Score for a player of your exact handicap. (So it doesn't use the same actual score twice to produce the 18 hole differential).

The higher differential is calculated because a player is only expected to "play to handicap" 20% of the time - the system accounts for this in the back 9 calculation which is what produces this slightly higher differential to combine with the front 9 score.
