Oh, fwiw, average weight in the UFC (assuming that every single fighter came in at exactly on point for weight class)
169.73lbs
(this is only active fighters)
So arguably, the divisions should be focussed around 170lb's.
each side of 170 should be a small gap as thats where the bulk of fighters are in weight, then as it gets to the extremes bigger gaps..
so something like
Strawweight 115
Flyweight 130
Bantamweight 145
Featherweight 160
Lightweight 170
Welterweight 180
Middleweight 195
Light Heavyweight 210
Heavyweight 265
so only a 10lb gap between feather > Lightweight > Welter as thats where the bulk of the athletes
then 15lb gaps elsewhere
that would keep the number of divisions the same, but would balance them in favor of number of athletes
