Data information
Understand the data behind NHL odds comparison, historical stats, fair-odds estimates and shot-price adjustments: what we collect, how we compare prices and how often the available records refresh.
Fair O/U is the decimal price implied by our player projection before bookmaker margin. The sportsbook columns show offered prices. A highlighted price is better than the model's fair price for that same line; it is an estimate, not a guaranteed outcome.
Read the odds board legend →Open a matchup before faceoff to see the latest available lines and starting goalies. Projected lineups can change. These pages show the available lineup information; they are not a record of the exact inputs used for every previous model run.
Check a matchup's lineup →The book screen shows recorded price and line movement for supported match markets and player props at the selected bookmaker. Charts end at the last available observation. Older match records without a timezone are labelled as source time and kept separate from records that can be converted to your local time.
Explore odds and line movement →Model notes explain our analysis and methods. The update feed records product and data changes, while game results and box scores show what happened on the ice.
Schedule, roster, play-by-play, shift, team and player-reference data are collected from several trusted hockey data feeds and reconciled into one internal model before they appear on the site.
Pinnacle, Bet365, Bethard, FanDuel, Betsson, Unibet, BetMGM and DraftKings, plus the Kalshi and Polymarket prediction markets on match markets — quoted at the executable best ask rather than a last trade, so an exchange price is comparable with a sportsbook's. That is the market price: the exchanges usually add a fee when you buy at it rather than placing your own limit order as a market maker. Scrapers run continuously and write to an immutable event log so we can replay the line history if a row ever looks wrong.
One row per (player × game × strength state).
Strength states cover 5v5 / 5v4 / 5v3 / 4v5 / 3v5 / 4v4 / 3v3
plus empty-net situations, so power-play and shorthanded splits are
first-class instead of derived after the fact.
Every shot event (goal / shot-on-goal / missed / blocked) carries coordinates, distance to net, angle and a danger-zone bucket (high / medium / low) so the "average shot distance" you see on a player card is calculated from actual rink coordinates.
We keep a season-level table per (player × team × season × regular/playoff) that's recomputed from the per-game rows. That's what powers the season-history table on every player page.
Completed-game stats are processed daily after the night's games, and rosters refresh weekly. Failed game syncs are retried on subsequent runs. Coverage and freshness depend on the source feeds and processing, so a missing or delayed record can still occur.
Match markets (moneyline, total shots,
home/away team totals) and player props (shots on goal, goals,
assists, points, PP-points, blocks, hits, faceoffs, first/last
goalscorer). Each row is one
(bookie, market, line, side) snapshot.
The live board compares current quotes. Historical player charts use available opening and final snapshots, with current quotes as a fallback. A first observed price may differ from a sportsbook's original opening price; history reflects the records we collected.
When books offer the same prop at different lines (e.g. shots 2.5 vs 3.5), we keep those selections separate. The default reference line prioritises the line offered by the most supported books, using bookmaker priority and price to break ties. Best-price and model comparisons use the same market, line and side, including available alternative lines.
Premium player odds history shows adjusted shots-on-goal prices when a matching team-shots line is available. With a 29-shot baseline, the over price is multiplied by 29 / team line and the under price by team line / 29. Recorded sportsbook prices remain visible alongside this adjustment; it is separate from the predictive model's fair odds.
