Everything in the WHS Formula — Explained
Short Grass doesn't just give you a number. It shows you every step of the calculation so you understand exactly how your Handicap Index is built.
Exact WHS Formula — No Guesswork
Short Grass uses the official World Handicap System formula: Handicap Index = average of the best 8 Score Differentials from your last 20 rounds. Every calculation is transparent — tap any round to see exactly how it contributed to your index.
- Official WHS formula (best 8 of last 20)
- Score Differential = (Adjusted Gross − Course Rating) × 113 ÷ Slope
- Soft and hard caps applied automatically
- Full calculation breakdown per round
Handicap Updates Automatically After Every Round
Post a score and your Handicap Index recalculates instantly. No waiting for a weekly GHIN update, no manual entry into a spreadsheet — your index is always current the moment you finish a round.
- Instant recalculation after each posted score
- No weekly update delay like GHIN
- Automatic exceptional score reduction
- Index history chart over time
Course Handicap Calculated for Every Tee
Your Handicap Index is just the starting point. Short Grass converts it to a Course Handicap for any tee box on any of 40,000+ courses: Course Handicap = Handicap Index × (Slope ÷ 113) + (Course Rating − Par).
- Course Handicap for any tee box
- 40,000+ courses with slope & rating data
- Playing Handicap for net stroke play
- Stableford points allocation included
Score Differential Breakdown Per Round
Every posted round shows its Score Differential — the key number that feeds your Handicap Index. See which rounds are helping your index, which are hurting it, and what score you'd need to improve.
- Score Differential shown for every round
- Which rounds are in your best-8 window
- Projected index after next round
- Rounds sorted by differential
