Accuracy ledger
A public, timestamped record of every tracked call and its graded outcome, wins and losses alike.
An accuracy ledger records each call before the game starts, then grades it automatically once the result is final. Because the entry exists before the outcome is known, it cannot be quietly revised afterwards.
A ledger worth trusting shows losses as prominently as wins, reports the sample size behind every rate, breaks results out by league and confidence tier, and counts the games where the model declined to publish a call.
AI4Gameday's ledger is public and deduplicated to one row per game, so a single fixture cannot be counted twice in the headline record.
