About these ratings

Ratings are domain-specific descriptive scales. Equal point differences across different domains do not imply equal absolute skill differences.

Takedown defense · Ratings V2: Recorded defense against incoming takedown attempts (takedown defense rate) under the Ratings V2 contract.
Wrestling · Ratings V2: Ratings V2 wrestling-offense score: recorded takedowns landed per round and takedown accuracy. Not ground control or complete grappling.
Chin · R1 research scale: Exposure-adjusted recorded knockdown resistance. This is not a direct biological measurement of chin, recovery, or injury resistance.
Cardio · R1 research scale: Recorded later-round striking activity and effectiveness retention. This is not a direct physiological fitness measurement.

Ratings V2 scores follow each fighter's latest recorded state; R1 research-scale scores are frozen through 17 Oct 2026. Recovery is separate metadata, not a rating. No combined rating exists.
