Calculation details

Rating breakdown for the past 12 months

Rating calculations are being updated. Current event, match and opponent details remain visible.

Classification evidence

Why ≤ 80 kg?

This outcome uses at most one unambiguous upper weight limit per completed ranking event from 2025-09-01 through 2026-08-31. Only the three most recent eligible events are considered, and the lightest verified upper limit is selected. A higher division is not treated as measured body weight.
