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.
