How PHIN works
PHIN is the league's GHIN-style index. Net differential per round =
(gross − rating) × 113 / slope,
rounded to one decimal.
The current PHIN is the average of the lowest N differentials in the most recent 20-round window, where N depends on how many rounds the player has posted (per the official USGA WHS table below), plus the table's adjustment.
| Rounds in window | Lowest N used | Adjustment |
|---|---|---|
| 3 | lowest 1 | −2.0 |
| 4 | lowest 1 | −1.0 |
| 5 | lowest 1 | 0 |
| 6 | lowest 2 | −1.0 |
| 7 | lowest 2 | 0 |
| 8 | lowest 2 | 0 |
| 9 | lowest 3 | 0 |
| 10–11 | lowest 3 | 0 |
| 12–14 | lowest 4 | 0 |
| 15–16 | lowest 5 | 0 |
| 17–18 | lowest 6 | 0 |
| 19 | lowest 7 | 0 |
| 20 | lowest 8 | 0 |
Glossary
- PHIN
- League handicap index, GHIN-style. Average of your lowest-N differentials in the last 20 rounds. Lower is better.
- Gross
- Your raw 18-hole score before handicap is applied.
- Net
- Score after handicap. On this site, the round-table "Net" column shows
72 + Hcp Diff— net relative to par 72. - Hcp Diff (Net Diff)
- Handicap differential — how this round adjusts your index.
(gross − rating) × 113 / slope. Lower is better. - Course Rating
- What a scratch golfer is expected to shoot from those tees. Bay Hill default: 71.5.
- Slope
- How much harder the course plays for a bogey golfer vs a scratch. 113 = average. Bay Hill default: 133.
- Net Double Bogey Cap
- Per WHS rules, a hole score is capped at par + 2 + handicap strokes received on that hole before the differential is calculated. Replaces the old ESC system.
- Bayhill HDCP
- Course handicap at Bay Hill (slope 133, rating 71.5). What you'd actually use for league play. Whole integer, half-up, capped at 18.
- Order of Merit
- Season points leaderboard. Top 10 auto-qualify for the playoffs.
- Falling off
- A round about to drop out of the rolling 20-round window the next time a player posts a new round.
- Best-N
- The N lowest differentials in the window — these are the rounds currently counting toward PHIN.
- R1 Bonus Strokes
- In the Finals (Round 1 only), seeds 1–5 receive additional strokes added to their Bayhill handicap: 1st +8, 2nd +5, 3rd +4, 4th +3, 5th +2. Seeds 6–11 play at true Bayhill. Handicaps capped at 18. Round 2 (top 5 advance) uses true PHIN with no adjustments. See Addendum 4.
- Wildcard Seed
- The 11th playoff seed earned by winning the Wild Card event (18-hole stroke play among non-qualifiers with 8 starts). The wildcard winner receives no R1 bonus strokes in the Finals.
