Weighting Breakdown

Goalie Weighting Breakdown



How Player Scores Are Calculated

Each category score is a weighted percentile (0-100) relative to all players in the pool.

Overall Impact — Category Weights

Category Base Weight Notes
5v5 Offense 27.5% Shifts with deployment (±5%) and receives part of leftover ST pool
5v5 Defense 21.5% Shifts opposite of offense; receives part of leftover ST pool
Production 20.0% All-situations production; usually fixed
Power Play from 11% ST pool w_pp = 0.11 × pp_share × pp_toi_ratio
Penalty Kill from 11% ST pool w_pk = 0.11 × pk_share × pk_toi_ratio
Penalties 5.0% Penalty ratio (PIM/60 ÷ Penalties Drawn/60), lower is better
Competition 7.5% Quality of competition faced
Teammates 7.5% Coach trust / usage proxy

Teammate Quality Adjustment (QoT SD Boost)

5v5 Offense and Defense metrics are adjusted for teammate quality using Evolving Hockey RAPM data. Players with strong teammates have their on-ice stats nudged down; players with weak teammates get a boost. This ensures the model rewards individual contribution, not just riding good linemates.

Step Detail
1. Offensive QoT composite RAPM xGF/60 (40%) + Off xGAR/60 (40%) + RAPM CF/60 (20%)
2. Defensive QoT composite RAPM xGA/60 (40%) + Def xGAR/60 (40%) + RAPM CA/60 (20%)
3. Convert to z-score z = (player QoT percentile − group mean) / group SD
4. Compute SD boost boost = −z × 0.5, capped at ±0.65
5. Apply to raw rates adj_metric = metric + boost × SD(metric across position group)
6. Direction Offense: better teammates → lower adjusted stats. Defense: better teammates → higher adjusted xGA (worse).

Affected offensive metrics: xGF/60, ixG/60, GF/60, HDCF/60, CF/60, FF/60, Rel xGF/60, Rel GF/60. Affected defensive metrics: xGA/60, GA/60, HDCA/60, CA/60, Rel xGA/60. The boost is position-group-specific (F vs D computed separately).

Penalties

Metric Weight Direction
Penalty Ratio = PIM/60 ÷ Penalties Drawn/60 100% Lower is better
