Market: First-5-innings Under 4.5 at +103 (pinnacle, quoted 10:30 AM CDT) · model expects ~4.6 runs · divergence 9 points — band B. B-band cutoffs fitted on OOF 2021-2024; the live record starts with this log. B cards in this market have won 49.2% of 620 out-of-sample grades (2021-2024), -2.0 points over break-even at the close. Not a betting-plan cell.

Honest row: grades cap at the band — extreme disagreement is as often our error as the market's. Moneyline gets no grade because our model hasn't beaten that market and says so. Graded against the line at grade time; the model was validated against closing lines. Weather from forecast; regrade if conditions flip. F5 grades ride a shorter history (2023-2025).
