Score Differential Formula:
| From: | To: |
Score Differential (SD) is a calculated value used in golf handicap systems to normalize scores from different golf courses with varying difficulty levels. It adjusts a player's gross score based on the course rating and slope rating.
The calculator uses the Score Differential formula:
Where:
Explanation: The formula adjusts the difference between the player's score and the course rating by the relative difficulty of the course compared to a standard course (slope rating 113).
Details: Score Differential is fundamental to modern handicap systems as it allows fair comparison of scores from different courses and tee boxes, ensuring equitable competition among golfers of varying skill levels.
Tips: Enter the adjusted gross score (total strokes after handicap adjustments), course rating (expected score for scratch golfer), and slope rating (measure of course difficulty). All values must be positive numbers.
Q1: What is the purpose of the 113 constant?
A: 113 represents the slope rating of a standard golf course, serving as the baseline for difficulty comparison.
Q2: How is Adjusted Gross Score different from actual score?
A: AGS is the actual score with adjustments for maximum hole scores (usually net double bogey) as per handicap system rules.
Q3: What do Course Rating and Slope Rating represent?
A: Course Rating indicates difficulty for scratch golfers, while Slope Rating measures relative difficulty for bogey golfers compared to scratch golfers.
Q4: How many Score Differentials are needed for a handicap?
A: Typically, handicap systems use the best 8 out of the most recent 20 Score Differentials to calculate a handicap index.
Q5: Can Score Differential be negative?
A: Yes, if the Adjusted Gross Score is lower than the Course Rating, resulting in a negative differential indicating exceptional performance.
