Actionable plays we fire pre-game: provisional (line-cooling, Rule C) plays at reduced stake. Provisional plays carry a smaller stake while that model is still proving out.

Reduced-stake plays (line-cooling)30-1566.7%

How to read this: the totals above are season-to-date and include our pre-launch backtest (Mar 27–May 11), when these rules were still being fit to past data — so they overstate what was bettable in real time. The honest out-of-sample record, since the rules locked on May 12: full-stake plays 6-4 (60.0%), reduced-stake plays 18-8 (69.2%). Records are recomputed straight from our logged game-by-game data every night. Stand-down (WATCH) results — 2-0 this season — are excluded entirely, even though they'd improve the headline.
