Methodology

Rocky Marciano ranks #107 with a 84.05 score on the 60-100 H&G All-Time Index. The public W-L-D row is unbeaten, so the loss-structure section adds no defeat caveats. The data-derived proxy signature-win marker points to a win over Joe Louis in 1951, because that defeated opponent carries a 2,121 Peak-form Elo in the same v1.2.2 export. Data Confidence is Medium, so the rating should be read with wider uncertainty. Peak-form Elo is 2,066 (±292), separate from the 60-100 career Index.
