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.
