Everything on this page follows the Adults | Kids switch. Gym rating = average Rating of the gym’s best 5 ranked athletes in that group (the first 5 listed); places count gyms with 5 ranked. “#12 in Canada” = the athlete’s place on their own All Canada board (Men, Women or Kids); Unranked = still provisional (too few matches or opponents, or too uncertain). Active = competed in the last 18 months (since 2025-04-24). Roster = athletes whose current gym is House of Combat; records count their whole history. Chart: monthly average of the best 5 skill ratings as they stood then (athletes with 6+ matches by then, active in the prior 18 months) — approximate. Data as of 2026-10-24.
