XIII. GrappleXmas BJJ Cup

The event score (0–100) is 50% the result and 50% the opponent’s last published level before the event. If that format has no rating, the other Gi or No-Gi rating is used as a proxy. Available opponent scores count equally within each format, then available Gi and No-Gi scores count equally. Equal scores share a place. The athlete’s own rating is not used. This score is separate from the official long-term rating and compares performances only within this event. Missing opponent scores are excluded and marked with an asterisk.

The academy score uses the same 50% result and 50% pre-event opponent level, using the other Gi or No-Gi rating as a proxy when that format has no rating. Each athlete with an available score then has equal weight. Matches between teammates stay outside the score; W-L and mat time still include them.

Coverage shows public athletes with at least one available opponent score out of active public participants in indexed youth divisions.

A match side without one clear academy registration is omitted. Unknown formats and matches without two clear academy registrations remain unassessed. Missing opponent scores are excluded; athletes without any available opponent score remain unassessed.
