Nationality splits

calls per 60 min of nationality TOI

Penalties on players of each nationality, normalized by that nationality's on-ice time in games this ref worked. Joint attribution: every penalty in a game credits both refs in the crew, so individual-call noise washes out at volume. Δ is the rate vs league baseline for the same nationality and scope. Rows under 60 minutes of nationality TOI are marked small; pattern language only — no intent claims.
