Radical transparency

Homepage cards pass published methodology gates. We label preliminary samples, shrink small-n deltas, and document what the data cannot prove.

Process over narrative

We measure historical tendencies in crew assignments and leverage-weighted whistle context. We do not frame officials as villains or sell unvalidated alpha.

Empirical validation

Signals are tested against external closing lines when data is available. We publish walk-forward results honestly, including when coverage is incomplete.

Research-first market

Built for research analysts, broadcast teams, and officiating intelligence - not unvalidated trader alpha.

Trust charter

Official whistle patterns show historical tendency in game environment, not guaranteed results.
