On the held-out 2025-26 season the model never trained on, the record was 231-121 (65.6%) across 352 unders over 129 slates. At flat $5 stakes and best-of-book price, a $100 bankroll grew to $456, a +20.2% ROI per bet, dipping as low as $78 (14% max drawdown) before compounding. Picks price at a median of -139. No flat-stake fudging, and we show the drawdown because the ride is not smooth.
