Frequently asked questions
How many rounds do I need for a handicap?
The World Handicap System needs at least 54 holes (three 18-hole rounds) to issue an initial index. More rounds give a more accurate handicap.
What's the 113 in the formula?
113 is the slope rating of a course of standard difficulty. Dividing by your course's slope adjusts the differential so handicaps are portable between courses.
