the letter is how far we sit from the market, not how sure we are
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 away starter back from a 30+ day MLB gap — established arm42%
The home team below league average in home runs, last 30 games27%
Umpire's strike zone has run narrower than the league this past year — fewer called strikesagainst the under19%
The away team allowing 5.1 runs a game, last 30 — above league average. Priced in, and it went too far — counts toward the under10%
The home team's catcher gains extra strikes behind the plate2%
Market: First-5-innings Under 4.0 at +104 (pinnacle, quoted 1:00 PM CDT) · model expects ~3.8 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.
Frozen B at 8:15 AM CDT · the number held. · both passes leaned this way.

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).
