How to read this profile

Rating is Glicko-2: the number shown is score - 2*RD (97.5% confidence lower bound), not raw skill. Inactive fighters "drift down" as RD grows - not because they got worse.

Hemaratings ratings don't factor in match scores, exchange counts, or doubles. Scout's score-margin and style metrics describe HOW a fighter fights, not the rating tier their results earned.

Hemaratings recomputes in batches days-to-weeks after events. A fighter's most recent tournament may not yet be reflected.
