About this rating
Rankings: H&G All-Time Index v2.0.0. Reflects fights up to , the most recent on record. The ratings are fixed to that point, so fights after it are not yet included.
The rating itself is built from the 34 bouts we hold full data for from 1979 to 1999, which is why this count differs from the professional record above.
For the data-minded
Peak-form Elo rating: 1,832 (peak dated 1999-06-01). This best-point rating sits on its own scale and is not directly comparable with the 0-100 index.
The peak estimate carries an uncertainty band of about ±428 Elo, so read close comparisons with care.
