UFC referee · active in the loaded archive 2018. 2 archived assignments.
The archive currently contains 2 bouts for Mark Simpson. That is enough to show assignments and outcomes, but not enough to turn a small difference in finish rate into a serious fight-week signal.
Descriptive history from the loaded archive. A referee does not choose the matchup, styles or scheduled length, so finish and decision rates are context, not a causal signal.
