the letter is how far we sit from the market, not how sure we are
THE PICTURE — what's driving the 1-point gapsized against each other · measured against the line — a stat the market already prices can point opposite its usual read

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).
