DISTRIBUTION
Live board. Empirical EWM + NegBin. The daily board runs an empirical estimator: exponentially weighted game-log average, blended with a usage-adjusted rate, scaled by an opponent-allowed factor, with a negative-binomial or normal spread fitted from the league's own game-to-game variance. NFL means are calibrated on 2021-2025 outcomes (accuracy only: the pool of quoted players is over-projected by 3-7%). It does not model injuries, lineups, minutes, weather or teammate absences, and it has not been validated against prices.
Research model. None trained for this stat.
WHAT THE LIVE BOARD LOOKS AT
- Exponentially weighted game-log average
- Usage-adjusted rate (time on ice)
- Opponent-allowed factor, shrunk and clipped

empirical_ewm mean, no opponent factor; as-of history (strictly earlier games); baseline = trailing-5 mean. Accuracy of the projection only; it says nothing about beating a price.

Result. No trained model; unvalidated
Against prices. No study has compared this stat with prices.
Record. No graded history is published for NHL projections: they are not logged to the public ledger, so there is no win rate or ROI to show.
Source: NHL shots-on-goal validation, 2026-10-14. MAE and CRPS: lower is better. The live board does not run the research model.
Goals per game from recent scoring rate and ice time. A rare-event market: most prices are one-sided anytime-scorer quotes.
