Why this ranking
Sumbu Kalambay ranks #701 with a 73.19 score on the 60-100 H&G All-Time Index. His standout win in our data is over Steve Collins in 1992, who reached a 2,052 Peak-form Elo, one of the stronger opponents on his record. In one case a result was later reversed: he beat Mike McCallum once, then lost to him in a later fight. Holding the score back, quality of opponents beaten sits below the field of ranked fighters in this release. Data Confidence is Medium, so the rating should be read with wider uncertainty. Peak-form Elo is 1,960 (±192), separate from the 60-100 career Index.

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 56 bouts we hold full data for from 1980 to 1993, which is why this count differs from the professional record above.
For the data-minded
Peak-form Elo rating: 1,960 (peak dated 1988-03-01). 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 ±192 Elo, so read close comparisons with care.
