1. What Is The WHS Handicap Index?

The WHS (World Handicap System) Handicap Index is a standardized measure of a golfer's demonstrated ability calculated against the slope rating of a course of standard playing difficulty. It was introduced in 2020 to create a unified handicap system worldwide.

2. How Does The Calculator Work?

The calculator uses the WHS Handicap Index formula:

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

Where:

\( HI \) — Handicap Index (unitless)
\( SD \) — Score Differential (unitless)
Best 8 — The 8 best score differentials from the most recent 20 rounds
0.96 — Net double bogey adjustment factor

Explanation: The formula takes the average of your best 8 score differentials from your last 20 rounds and applies a 96% multiplier to create your handicap index.

3. Importance Of Handicap Index Calculation

Details: The handicap index allows golfers of different skill levels to compete fairly. It provides a consistent measure of playing ability that can be used on any golf course worldwide under the WHS system.

4. Using The Calculator

Tips: Enter your 8 best score differentials from your most recent 20 rounds. Score differentials are calculated based on your gross score, course rating, and slope rating. Lower score differentials indicate better performance.

5. Frequently Asked Questions (FAQ)

Q1: Why are only the best 8 of 20 scores used?
A: Using the best 8 scores provides a measure of a golfer's potential ability rather than average performance, creating a more equitable system.

Q2: What is the purpose of the 0.96 multiplier?
A: The 96% multiplier (net double bogey adjustment) helps ensure that a handicap index reflects a golfer's potential ability rather than their average performance.

Q3: How often is the handicap index updated?
A: Under WHS, handicap indexes are updated daily based on newly submitted scores, providing a current reflection of a golfer's ability.

Q4: What is a score differential?
A: A score differential is calculated as: (113 / Slope Rating) × (Adjusted Gross Score - Course Rating - PCC adjustment). It normalizes scores across different courses.

Q5: How does WHS differ from previous handicap systems?
A: WHS unifies six different handicap systems into one global standard, using consistent calculations and daily updates for greater accuracy and fairness.
