How this is graded

This system was published elsewhere; we graded its rule on every game it fit in 2021 to 2026 at our closing consensus prices. ROI is profit per unit staked after the vig. We list a system only if it made money over the whole sample and in both the earlier and later seasons, on 50 or more decided bets. Rates exclude pushes; n counts decided bets.
