Composite scores
Headline summary numbers that combine many inputs into a single tier-able rating.
Consistency Index
How predictable a ref's calls are vs. their own per-60 baseline. Lower = more consistent.
Discipline Rating
Misconducts + bench minors per 60. Captures how often a ref reaches for the heavy hammer.
Home Cooking Coefficient
Pattern of home-vs-road call rates. League average ≈ 0; positive = home call rate exceeds road, negative = the reverse.
Leverage Grade
A+ → D ranking of how much a ref's call rate shifts in OT and playoff games vs their regulation baseline.
Core rates
The plain-English per-60 numbers. Foundation for every higher-level stat.
Penalties Per 60
Total penalties called / games. Denominator is games (not raw ice time) because OT is rare.
Per-call-type rates
17 canonical call types each tracked per-60 with league percentile (Tripping, Hooking, Holding, …).
Penalties Taken / 60
Player metric. How often this skater gets whistled per 60 minutes of ice time.
Penalties Drawn / 60
Player metric. How often this skater draws calls per 60 minutes of ice time.
Temporal patterns
When does this ref reach for their whistle within a game? Drift, density, suppression.
First Penalty Timing
Average game time of a ref's first P1 call. Earlier = more proactive game-setting.
Gap Between Calls
Average seconds between consecutive calls in a game. Drives Gap Rhythm.
Gap Rhythm
STDDEV of gap times. Lower = steady cadence; higher = bursty calling.
Penalty Density by Period
Per-60 split across P1 / P2 / P3 / OT. Shows whether a ref tightens or loosens late.
Late-Period Suppression
How much call volume drops in the final 5 minutes of regulation vs the rest of the game.
Power Play Chain Rate
How often a ref carries successive PP calls vs a single one. Captures escalation behavior.
First / Final 5-Minute Delta
Per-60 difference between opening and closing 5 minutes of each period.
OT Call Rate
Penalties per 60 in overtime. OT is rarely whistled across the league; high values stand out.
Situational splits
Calls by score state and game leverage — does this ref tighten in close games?
Score-State Calling
Per-60 split across tied / one-goal / blowout game states.
One-Goal Game Suppression
How much calling drops in P3 of one-goal games vs the league baseline.
Make-Up Window Rate
Share of penalties followed by a cross-team penalty within 10 minutes — captures perceived 'evening out'.
Crunch-Time Discipline
Player metric. Penalties taken in 3rd/OT, last 5 min, ≤ 1-goal games — per game played. Higher = worse late-game discipline.
Player-context calling
How does a ref treat star forwards vs depth players, captains vs rookies?
High-TOI vs Low-TOI Call Ratio
Penalty rate on STAR / TOP-6 players vs depth players, normalized for ice time.
TOI Tier
Position-aware tier the player rolls up to: Forward STAR / TOP 6 / MIDDLE 6 / DEPTH / 4th, Defense Top / Middle / Bottom Pair, Goalie Star / Starter / 1A / 1B / Backup / 3rd / Rookie.
Ref Affinity Δ (taken)
How a specific ref's per-60 taken rate on this player differs from the player's own league baseline.
Ref Affinity Δ (drawn)
How a specific ref's per-60 drawn rate for this player differs from baseline.
Team-level officiating
How a team has been officiated — who works them most, who has the largest positive vs negative penalty differential.
Penalty Differential vs Team
PF − PA across all of a ref's games with this team. Positive = team drew more than they took under this ref.
PP Opportunities Differential
PP opportunities for the team − against. Closely tracks penalty differential but isolated to power-play exposure.
Most Favorable / Unfavorable Refs
Ranked lists scoped per team based on cumulative differential, sample-filtered.
Home / Road Differential (team)
How much a team's penalty profile shifts at home vs on the road.
Team Discipline Index
Team's overall composite of misconducts / fights / late-game escalation behaviors.
Team Call-Type Profile
Top types this team takes and draws, with league baselines for context.
Coach challenges
Off-ice judgment calls and how each ref's reviews resolve.
Coach Challenge Record (ref)
Per-ref upheld / overturned counts on coach challenges, scoped to the active season.
Framing & sample minimums
How we present numbers and when we mark them as small-sample.
