How we verify our projections

Every tracked prediction is archived before games begin, then compared against final results after games complete.

The numbers below are read directly from our tracking and validation files — the same artifacts our internal monitoring uses. Nothing on this page is estimated or back-filled.

Some sports have deeper historical grading than others. We only publish metrics where current verified tracking is available.
