XII. GrappleXmas BJJ Cup

The event score (0–100) is 50% the result and 50% the opponent’s last published level before the event. Opponents count equally within each format, then Gi and No-Gi 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, compares performances only within this event and appears only when every assessable opponent has a public pre-event rating.

The academy score uses the same 50% result and 50% pre-event opponent level, then gives each assessed athlete equal weight. Matches between teammates stay outside the score; W-L and mat time still include them.

Coverage shows public athletes with a complete score basis out of active public participants in indexed youth divisions.

A match side without one clear academy registration is omitted. Unknown formats, matches without two clear academy registrations and opponents without a public pre-event rating remain unassessed.
