methodology

source
Wikipedia fighter pages are scraped into fight records; duplicate A/B-side entries are collapsed into canonical fights.
model
Glicko/Elo-style replay. Rankings use all-time score; hover shows live rating.
inactivity
Scraped fighters marked active with no fight in over three years are set inactive in the computed snapshot. Active fighters get the small dot.
weight class
Curated fighters use seed data; other fighters use the first scraped division after normalization. The main list is pound-for-pound, not per-division.
outcomes
No-contests are skipped for rating updates. Draws score 0.5/0.5. Method is stored as metadata but does not change the rating delta.
