Projection Scoreboard

How it works

Before every race or game, the projection file is published and timestamped, and a SHA-256 fingerprint of that file is recorded so anyone can verify the numbers were not edited later. After results are in, those locked projections are graded on simple measures: average miss in DraftKings points (MAE), top-10 and top-5 hit rate for NASCAR, rank correlation, and a comparison to a free public projection set. Wins and losses are both shown.
