Your Yahoo! Handicap Rating is calculated based on the last 20 rounds of golf played. The best 10 of those 20 rounds are used—taking into account the slope and course rating for the courses played—to arrive at your current Yahoo! Handicap Rating. If you've played fewer than 20 rounds, the best 10 still count toward your Yahoo! Handicap Rating; if you've played fewer than 10, all rounds are included in the calculation.
Please note: The Yahoo! Handicap Rating has been solely developed by Yahoo! Inc., and is in no way authorized by or connected with the USGA.
