How are NFL betting systems graded?▾
Each system's picks are graded against the closing line of the sharpest available market. Wins and losses count only after settlement. ROI and closing line value (CLV) are calculated per pick, and the aggregate metrics shown here reflect actual bet outcomes — no back-tested hypotheticals.
What sample size is meaningful for a NFL betting system?▾
A minimum of 15-20 graded picks is the floor for statistical meaning, and 50+ is where a real edge typically shows up. Systems with very small samples can look strong or weak purely from variance, so sample size is a stronger trust signal than a high hit rate alone.
