How It Works
Selects the lowest 8 of the most recent 20 official Score Differentials and rounds their mean to one decimal. Enter official differentials that already include course/slope ratings and playing-conditions adjustments.
Scope and Limitations
- This is the uncapped 20-score base estimate, not an official Handicap Index. Exceptional-score reductions, soft/hard caps, committee adjustments and fewer-than-20-score rules are excluded.
