the letter is how far we sit from the market, not how sure we are
THE PICTURE — what's driving the 2-point gapsized against each other · measured against the line — a stat the market already prices can point opposite its usual read
Wind blowing in, ~8 mph net30%
The away starter strikes out 18.7% of batters, adjusted — a lower strikeout rate than averageagainst the under23%
Umpire's strike zone has run wider than the league this past year — more called strikes22%
The home team has the lefty-righty edge in the lineupagainst the under13%
Team strength & form leans under — mostly the away team4%
WHAT WE COULDN'T SEEpriced into our number — not evidence about this game
No 2025 record of strikes gained behind the plate for the away catcher — graded at league averageagainst the under8%
Market: First-5-innings Under 4.5 at -106 (pinnacle, quoted 2:00 PM CDT) · the full picture prices it +102 · model expects ~4.9 runs · divergence 2 points — band none.
SITUATIONAL CONDITIONSdetected for this game · not a grade input — anything that carries weight appears in THE PICTURE

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).
