Why this placement
Why this placement
Rocky Marciano ranks #54 with a 87.68 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 v1.2.3 export. Data Confidence is Low, so the rating should be read with wider uncertainty. Peak-form Elo is 2,066, separate from the 60-100 career Index.
