    "reasoning": "I've found several interesting patterns, but I need to verify the most counterintuitive one. The evidence shows that when Fighter B has physical advantages (taller, longer reach, heavier), they win MORE often than when Fighter A has those same advantages. Specifically: B wins 16.47% when they have longer reach vs A winning 12.63% when A has longer reach; B wins 16.07% when taller vs A winning 11.1% when taller. This is backwards from what we'd expect - the underdog (B) appears to leverage physical advantages MORE effectively than the favorite (A). But I should verify if there's a confounding factor - perhaps when B has physical advantages, they also have comparable experience. Let me check the interaction between physical and experience advantages.",
