WHO THEY
ACTUALLY FOUGHT

A record says how often a fighter won, not against whom. These ratings weigh every result by the opponent's strength at the time, then compare this fighter with the 59 rated fighters on the UFC women's strawweight roster (anyone with a UFC bout in the last two years or one booked).
