UFC bouts only, so these will not add up to the record above. Counts rather than rates: two knockouts in three wins is not a 67% finisher.

As the fight goes on

Which measure to show

Significant strikes landed, per minute fought. Every round is measured against round one, except rounds reached by fewer than 3 bouts, which are dimmed and left uncompared.

Only fights that reached a round count towards it, so later rounds are a smaller sample.

Earned Accuracy

How hard the opponents on this record were to hit at distance, and whether they beat it. Distance strikes only, so nobody gets credit for accuracy they picked up hammering someone already flat on the floor.

Coverage
from real records

Too much of this record was set against opponents who had no distance history of their own yet. The expected number would mostly be the division average wearing a disguise, so it's held back.

The fine print

Distance strikes only

Nothing thrown in the clinch or on the ground counts. Those land at about 72% and 71%, against 44% at distance, so a blended accuracy mostly measures where a fight happened. Rank the sport that way and its best strikers are all wrestlers.

One pass, not a rating

How much each opponent lets through is taken raw. It isn't adjusted for who they fought, so a fighter whose opponents all had soft schedules comes out looking better here than they are. Running it to convergence is a later job.

Coverage, and who gets ranked

Coverage is how much of the expected number came from the opponents' own records instead of the division average. Under 65% it's mostly the division talking, so the comparison gets hidden. Same for anyone under 5 qualifying bouts, or under 300 distance strikes of their own, which is where an accuracy still moves on a single exchange. Miss any of the three and you'll see what they landed, nothing else, and they stay out of any ranking.

Short records get pulled to the middle

An opponent who hasn't been shot at much gets dragged toward their division's average, and the drag fades as their record fills in. At 60 distance strikes faced, their own record and the division average count for the same.
