Frequently asked questions
What's adjusted gross score?
Your actual score with a maximum per hole applied (net double bogey under WHS). It stops one disaster hole from inflating your handicap.
Why does score differential use course rating and slope instead of just par?
Par alone ignores how difficult a course actually plays. Course rating reflects the expected score of a scratch golfer and slope reflects relative difficulty for a bogey golfer, so two courses with the same par can produce very different differentials for the same raw score.
