Publishing threshold

Waiting for a representative sample

Combat Edge does not publish an average or median gym Elo until at least 3 active fighters have Elo. Individual fighter ratings remain visible while Synthesis BJJ is below that threshold.

This page is excluded from the official leaderboard until the gym reaches 5 active fighters. Gym pages require at least 3 active fighters before search indexing.
