All methods
Score-state splits
ExperimentalA derived construct without out-of-sample validation - read as informed opinion.
What it means
Production while tied or trailing, against the player's own overall rate.
How it's computed
GS/60 in tied-and-trailing ice time minus overall GS/60.
What's validated - and what's not
A descriptive single-season split shaped by deployment and score effects - not shown to repeat year over year, so it describes what happened, not a trait.
Coverage
2010-11 to present (needs shifts).
Provenance
Forensic Hockey original - built from official NHL play-by-play and box scores.
A first-party construct. We never adopt an idea on authority alone; the methodology stance is recorded in our research ledger.
Our research ledger - every source we tested, adopted, or rejected →Tiers are a promise, not a style. Reconciled is checked against the official NHL record; Validated is tested on data the model never fit; Experimental is a derived construct without out-of-sample validation - read it as informed opinion. When in doubt we take the lower tier.
