OddsRecord

Anyone can publish a forecast. Almost nobody publishes the score.

OddsRecord will publish a calibrated win probability for every game, and the full scored record behind it — every forecast timestamped before tip-off, scored automatically afterwards, with sample sizes on every number and a file you can download and recompute yourself.

What a calibration record looks like

80–90%

Empty on purpose. The record starts the day the first forecast is published, and it will never be back-filled.

What this is not

Why the sample size matters more than the streak

Over 100 bets, someone with no skill whatsoever finishes between 43% and 62% about 95% of the time. Luck is worth roughly nine points over that stretch. A genuine edge is worth about one and a half. That is why a hot season proves nothing, and why the only honest thing to publish is the whole record with the count beside it.
