How to use the fair line
At −110 vig, the model sees value on the OVER at lines below 1.0 and on the UNDER at lines above 1.0. Between those boundaries, neither side clears the vig-adjusted breakeven. At the fair line (1.5), no-vig breakeven odds are +164 on the OVER (37.91% win prob) and −164 on the UNDER (62.09% win prob).

Model limitations
PropStein publishes model limitations alongside every page. Roles and thresholds are provisional pending chronological holdout validation. In our published week-1 holdout evaluation the model's Brier score trailed the naive baseline; we treat that as an open defect, not a marketing problem, and we publish recalibration results as they land. Snapshots are taken pre-kickoff; quotes age and lines move, so every number here carries a timestamp and a verification state. Route-participation and late-scratch information are not fully modeled. Nothing on this site is betting advice.
