How this is worked out
- Reach and height are read from the fighter's English Wikipedia infobox and normalised to centimetres.
- Reach advantage is (reach − height) ÷ height, expressed as a percentage, so fighters of different sizes compare directly.
- The percentile is that figure's rank among the 594 heavyweight Boxing fighters in this dataset — not among everyone who has ever fought.
Reach advantage = (reach − height) ÷ height × 100
