All High conf only
Results — flat 1 unit, at −110 and at the real price
A unit is one flat bet. Winning at −110 returns 0.91u, losing costs 1.00u, so break-even is 52.38%. Accuracy is not money. −110 is a fiction for this model. It picks favourites at a median closing −139, where break-even is 58.1%, so the −110 column flatters it by a wide margin. The right-hand column prices every pick at what it actually closed at.
Confidence modelling — non-overlapping bands
Disjoint bands, so each row stands alone. The cumulative tiers below nest every high-confidence pick inside every lower one, which flatters the weaker tiers.
