NHL FireFactor Accuracy

The settled ledger: for each of the last 10 completed slate days, the strongest pre-game FireFactor leans — recomputed from only the game logs available before that slate — checked against what actually happened. Every row links to the player’s full read.

How to read this honestly: rows are recomputed after the fact from the same public game logs the live board uses, settled at the line a book actually posted for that slate where we still have it (hover a line to see which) and at our own book-style half-point line otherwise. They omit the matchup / Vegas / pace context the live board folds in, because that context can’t be faithfully reconstructed later — so these are conservative reads. A small sample of settled days proves nothing either way; the point is transparency, not a win-rate claim. Descriptive research — never predictions, picks, or betting advice. See the methodology for the exact math.
