I did not play a hole. What score do I post?

For a score to be acceptable for handicap purposes, at least 9 holes that have a 9-hole Course Rating™ and Slope Rating™ must be played. If between 10-17 holes are played (typically due to darkness, inclement weather, or match play), hole-by-hole score entry is required for the holes played.

Once a score is posted for the holes played – for example, holes 1-16 – a Score Differential™ will be created based on the 16 holes played, and the expected Score Differential™ for two holes not played will be added to that value to produce an 18-hole Score Differential.

For a player who has yet to establish a Handicap Index (working toward posting scores from 54 holes played), only the 9- and 18-hole score posting option will be available.
