❓ Common questions
- What is course rating?
- Course rating is the expected score for a scratch golfer (0 handicap) on that course under normal conditions. It's usually between 67 and 77.
- What is slope rating?
- Slope rating measures the relative difficulty of a course for a bogey golfer compared to a scratch golfer. It ranges from 55 to 155, with 113 being the standard.
- How many rounds do I need?
- You need at least 3 rounds to calculate a handicap. With fewer than 20 rounds, a different number of differentials are used (e.g., best 1 of 3, best 2 of 5, etc.).
- What does the 0.96 multiplier do?
- The 0.96 'bonus for excellence' slightly reduces the handicap index to reward better players and keep the system competitive.
- What is a good handicap?
- The average male golfer has a handicap around 14–16. Female average is around 24–28. Single-digit handicaps (below 10) are considered good golfers.
