1. What is the WHS Handicap Index?

The World Handicap System (WHS) Handicap Index is a measure of a golfer's demonstrated ability calculated against the Slope Rating of a golf course of standard playing difficulty. It allows golfers of different abilities to compete fairly.

2. How Does the Calculator Work?

The calculator uses the WHS Handicap Index formula:

\[ HI = \left( \frac{\text{Sum Best 8 Score Differentials}}{8} \right) \times 0.96 \]

Where:

\( HI \) — Handicap Index (unitless)
\( SD \) — Score Differential (unitless)
Best 8 — The 8 lowest score differentials from the last 20 rounds
0.96 — Bonus for Excellence multiplier

Explanation: The system takes your best 8 score differentials from your most recent 20 rounds, calculates the average, then applies a 0.96 multiplier to slightly favor better performance.

3. Importance of Handicap Index

Details: The Handicap Index is essential for fair competition, allowing golfers of different skill levels to compete equitably. It's used worldwide under the unified World Handicap System.

4. Using the Calculator

Tips: Enter your score differentials separated by commas. You need at least 8 scores for calculation. The calculator will automatically select your best 8 scores (lowest values) for the calculation.
