Real-world odds

—

No independent base rate yet. Until we connect one (sportsbook consensus, forecasts, the score), the market's own price is the best public forecast, and the fee sits on top of it.

Luck needed meter

84% 😈

Mostly luck. The market itself expects the favorite to lose this often; the fee is the only certainty.
