the letter is how far we sit from the market, not how sure we are
THE PICTURE — what's driving the 4-point gapsized against each other · measured against the line — a stat the market already prices can point opposite its usual read
The home starter strikes out 30.9% of batters, adjusted — a higher strikeout rate than average44%
89°F — heat carries the ballagainst the under27%
Both catchers gain extra strikes behind the plate17%
Team strength & form leans over — mostly the away teamagainst the under8%
The home team below league average in home runs, last 30 games5%
Market: First-5-innings Under 4.0 at -108 (pinnacle, quoted 4:30 PM CDT) · the full picture prices it +104 · model expects ~4.4 runs · divergence 4 points — band none.
Frozen B at 8:15 AM CDT · the market came toward our number · final grade no lean. · the morning pass leaned B; this pass stands down.
SITUATIONAL CONDITIONSdetected for this game · not a grade input — anything that carries weight appears in THE PICTURE
none detected for this game
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).
