Let me explore key dimensions: (1) ranking dynamics - how often do lower-ranked fighters beat higher-ranked ones (upsets), (2) physical advantages - the distribution and impact of reach/height differentials, (3) stance matchups - how orthodox vs southpaw combinations affect outcomes, and (4) how fights end. I'll start by examining ranking data and upset patterns, since rankings provide a clear expectation that outcomes can violate.",
