Parlay & margin auditor
Use the complete market for each leg, not just your pick. This estimates the pricing margin; it cannot reveal true chances.
Estimated all-leg probability: 12.5%
Model fair decimal odds: 8.00
Estimated bookmaker margin: 12.5%
Model expected net per $100.00: -$12.50
Assumes independent legs and proportional margin removal from complete markets. Same-game or correlated legs, boosts, pushes, voids and missing outcomes invalidate this model. Expected net is a repeated-bet average, not a prediction. A negative margin is not a betting recommendation.
