How this ranking is built

Computed across every one of the 5,754 fighters published here — not a curated list, and not weighted by fame.
A fighter appears only where the figure is computable from their own source. A missing value is an absence, never a zero, so it does not sink a fighter to the bottom of the table.
Ties keep their source order rather than being broken by a second metric the reader did not ask for.
