1. What is the WHS Golf Handicap System?

The World Handicap System (WHS) provides golfers with a unified and consistent handicap index that can be used worldwide. It allows golfers of different abilities to compete on a fair basis.

2. How Does the Calculator Work?

The calculator uses the WHS Handicap Index formula:

Where:

• \( HI \) — Handicap Index (unitless)
• \( SD \) — Score Differential (unitless)
• \( \text{Sum Best 8 SD} \) — Sum of the best 8 score differentials from your last 20 rounds
• \( 0.96 \) — Bonus for Excellence multiplier

Explanation: The system takes your best 8 score differentials from your most recent 20 rounds, averages them, and applies a 96% multiplier to determine your handicap index.

3. Importance of Handicap Index Calculation

Details: A proper handicap index allows golfers to track their progress, compete fairly in tournaments, and play against golfers of different skill levels on equal terms.

4. Using the Calculator

Tips: Enter your 8 best score differentials from your last 20 rounds. Score differentials should be positive numbers representing your performance relative to course difficulty.

5. Frequently Asked Questions (FAQ)

Q1: What is a score differential?
A: Score differential measures your performance in a round, calculated as: (Adjusted Gross Score - Course Rating) × 113 / Slope Rating.

Q2: Why use only the best 8 of last 20 rounds?
A: This focuses on your potential ability rather than average performance, rewarding consistency and peak performance.

Q3: What is the 0.96 multiplier for?
A: This "Bonus for Excellence" encourages improvement by slightly reducing the handicap index of better performers.

Q4: How often should I update my handicap?
A: Handicaps should be updated after each acceptable round, with revisions typically occurring daily or weekly.

Q5: Can I have a negative handicap index?
A: No, the minimum handicap index is 0.0 (scratch golfer). Professional golfers typically play to plus handicaps.
