Why this placement
Why this placement
Billy Conn ranks #52 with a 87.85 score on the 60-100 H&G All-Time Index. The data-derived proxy signature-win marker points to a win over Young Corbett III in 1937, because that defeated opponent carries a 1,929 Peak-form Elo in the same v1.2.3 export. The parsed-opponent data records one reversal pattern: he later lost to Teddy Yarosz after an earlier win over the same resolved opponent. Data Confidence is Low, so the rating should be read with wider uncertainty. Peak-form Elo is 1,961, separate from the 60-100 career Index.
