1. What is the Handicap Index?

The Handicap Index (HI) is a measure of a golfer's potential ability under the World Handicap System (WHS) used by Golf Canada. It represents the number of strokes a player needs to play to par on a course of standard difficulty.

2. How Does the Calculator Work?

The calculator uses the WHS 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 lowest score differentials from the last 20 rounds
0.96 — Net double bogey adjustment factor

Explanation: The formula calculates the average of the best 8 score differentials from a golfer's most recent 20 rounds, then applies a 96% multiplier to determine the final handicap index.

3. Importance of Handicap Index

Details: The Handicap Index allows golfers of different skill levels to compete fairly. It's used to calculate Course Handicap for specific courses and ensures equitable competition across various playing conditions.

4. Using the Calculator

Tips: Enter at least 8 score differentials (one per line). The calculator will automatically select the best 8 scores and apply the WHS formula. Score differentials should be calculated based on course rating and slope.

5. Frequently Asked Questions (FAQ)

Q1: What is a Score Differential (SD)?
A: Score Differential is calculated as: (113 / Slope Rating) × (Adjusted Gross Score - Course Rating - PCC adjustment). It normalizes scores across different courses.

Q2: Why use only the best 8 of 20 scores?
A: This system focuses on a player's potential ability rather than average performance, rewarding consistency and peak performance.

Q3: What does the 0.96 multiplier represent?
A: The 96% multiplier (net double bogey adjustment) ensures the handicap index represents a player's potential ability rather than average performance.

Q4: How often is the Handicap Index updated?
A: Under WHS, handicaps are updated daily based on newly submitted scores, providing a current reflection of a player's ability.

Q5: What's the difference between HI and Course Handicap?
A: Handicap Index is portable, while Course Handicap is specific to each course: CH = HI × (Slope Rating / 113) + (Course Rating - Par).
