Sportsbook Rating
How WSTF rates player vs operator betting coupon settlements — PREGAME and LIVE kept separate, no stake data ever used.
What is scored
Only ACCEPTED Sportsbook partner events from VERIFIED/UNVERIFIED partners, resolved to a linked WSTF player, with a canonical result (WON/LOST/VOID/CANCELLED) and total coupon odds >= 1.01. HELD, REJECTED and non-Sportsbook events are never scored.
Pregame & Live are separate
PREGAME and LIVE Sportsbook events are independent datasets with their own maturity, statistics and ranks. Sportsbook Overall is the exact sum of Pregame + Live (no mixing with Arena / Challenge / Strike5 / WSTF Overall).
Success rate
SUCCESS = WON / (WON + LOST) × 100. VOID / CANCELLED / PENDING coupons are excluded from the denominator; a player with 0 settled coupons shows N/A, never 0%.
Difficulty bands
Every coupon is classified by its total odds into one of 14 difficulty tiers (MINIMAL → GOLD). Difficulty describes the coupon, not the player; low tiers are not failure states.
Points — Model C
WON coupons: +10 × (min(TOTAL_ODDS, 20.00) − 1). LOST coupons: a Decimal-exact piecewise-linear curve anchored at (1.01, −150) · (1.10, −100) · (1.20, −35) · (1.50, −15) · (1.70, −12) · (2.00, −10); losses at ≥ 2.00 are flat −10. VOID/CANCELLED coupons are always 0 points.
Scoring cap
To prevent single lottery coupons from dominating, points are computed on min(odds, 20.00). The actual odds are always stored and displayed on the Passport (e.g. a +47.50 GOLD winner shows 47.50, not 20.00).
Confidence
CONFIDENCE = SETTLED / (SETTLED + 20). Small samples contribute less to the rating regardless of success rate.
Rating
RAW = 1500 + 2 × PERFORMANCE/100 × CONFIDENCE, where PERFORMANCE/100 = (POINTS / SETTLED) × 100.
Maturity
0–4 settled: NEW (preview only, not on the leaderboard). 5–14: PROVISIONAL (rating clamped to 1300–1700). 15–29: RANKED (clamped 1200–1900). 30+: ESTABLISHED (no cap). Pregame, Live and Overall each have their own maturity.
No stake influence
The engine never reads stake, turnover, deposits, withdrawals, wallet balance or any monetary field. Two players with identical results and different stakes have identical ratings. Sportsbook Rating is NOT ROI.
VOID / CANCELLED
Zero points, excluded from WON/LOST, from success-rate denominator and from average odds.
