Market: First-5-innings Under 5.5 at -111 (pinnacle, quoted 4:30 PM CDT) · the full picture prices it -101 · model expects ~5.9 runs · divergence 0 points — band none.
Frozen C at 8:15 AM CDT · the market came toward our number · final grade no lean.
SITUATIONAL CONDITIONSdetected for this game · not a grade input — anything that carries weight appears in THE PICTURE
Heavily used bullpenHot day (90°+)
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).
