THE PICTURE — what's driving the 10-point gapsized against each other · measured against the line — a stat the market already prices can point opposite its usual read
The home starter has thrown 476 pitches over 30 days26%
The home team below league average in home runs, last 30 games25%
The away team playing like a .331 club right now22%
Umpire's strike zone has run wider than the league this past year — more called strikes17%

Market: First-5-innings Under 4.5 at -119 (pinnacle, quoted 4:30 PM CDT) · model expects ~4.4 runs · divergence 10 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).
