Game Score Value Added
ExperimentalA derived construct without out-of-sample validation - read as informed opinion.
What it means
Game Score above a replacement-level player, converted to wins.
How it's computed
(GS/60 − replacement level) × ice time × a points-per-Game-Score slope.
What's validated - and what's not
An unvalidated conversion: the replacement line and slope are chosen, not tested out-of-sample, and the slope partly contains the player's own scoring. Useful for ranking, soft on magnitude.

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.
