Results explained
Course handicap ≈ Index × (Slope ÷ 113) + (Course Rating − par). A playing handicap may then take 95% or 100% depending on format — not modeled.
Quick reference: WHS sketch
Slope 113 and rating = par means course handicap ≈ index.

How the estimate is built
CH = Index × (Slope/113) + (CR − par).
Example scenario
Index 12.4, slope 128, CR 72.1, par 72 → 12.4 × 1.133 + 0.1 ≈ 14.1.
