How this is worked out
- Measurements and records are read from the fighter's English Wikipedia infobox; the fight list is parsed from the article's own results table.
- Reach advantage is (reach − height) ÷ height as a percentage, so fighters of different sizes compare directly.
- Percentiles rank this fighter among the 299 welterweight MMA fighters in the dataset — chosen because it is the most specific group of at least 30 that this fighter belongs to.
Reach advantage = (reach − height) ÷ height × 100
