THE PICTURE — what's driving the 9-point gapsized against each other · measured against the line — a stat the market already prices can point opposite its usual read
The home starter likely goes only an inning or two — relievers cover most of the game. Priced in, and it went too far — counts toward the under41%
The away team below league average in home runs, last 30 games28%
Team strength & form leans over — mostly the away teamagainst the under18%
Behind the plate leans under9%
Park & environment leans overagainst the under4%
Market: First-5-innings Under 4.5 at -109 (pinnacle, quoted 11:30 AM CDT) · model expects ~4.7 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.
FIRST 5Frozen no lean at 8:15 AM CDT · the market moved away from it · final grade B. · new at this pass — the morning pass had no lean.
TOTALFrozen no lean at 8:15 AM CDT · the market moved away from it · final grade C.

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).
