Why this placement

Methodology

Marvin Hagler ranks #46 with a 89.24 score on the 60-100 H&G All-Time Index. The loss-structure check asserts no stoppage losses in the release rows. The data-derived proxy signature-win marker points to a win over Thomas Hearns in 1985, because that defeated opponent carries a 1,982 Peak-form Elo in the same v1.2.2 export. The strongest model lifts are sustained top-level career signal (well above the typical top-1000 fighter) and sustained head-to-head rating level (above the typical top-1000 fighter). Peak-form Elo is 2,059 (±227), separate from the 60-100 career Index.
