How BTR Win Probability is Calculated

Standard sports statistics are completely blind to real-world context like team motivation, tactical lineup shifts, or irregular lower-league match outcomes.

Our BTR Win Probability uses a double-layered, anomaly-resistant algorithm to cut through market noise and deliver the authentic layout of a match:

Historical Tipster Predictions: We compare today's prices with a proprietary archive of over 1,000,000 settled tipster predictions tracked since 2015, showing how real published picks performed in the same odds range, sport, market, period, and outcome. This matters because very few prediction sites can support their probabilities with such a large transparent record of real historical picks.

Recent Hypothetical Picks: We also backtest recent settled odds markets by treating each available outcome as a hypothetical pick, then checking it against the real result. This shows how similar prices performed in live match conditions, even when no tipster selected that outcome.

BTR Probability Blend: The final percentage balances bookmaker implied probability, historical tipster predictions, recent hypothetical picks, market movement, and bookmaker consensus. This helps reduce blind trust in very short odds while still rewarding prices that have performed well in similar conditions.

By fusing traditional lines with a decade of community conviction, we provide an unfiltered, back-tested projection you can trust.
