Lol it still doesn't compare to the other divisions.
Look at Maldonaldo for an excellent example.
Let's look at the math
Without Loss of Generality let weight1 > weight2
% difference in weight = (weight1 - weight2)/(weight2) * 100
Note: an average weight cut is roughly 20 pounds for each division
make the assumption that an average WW today weighs 190 on fight night, an average MW weighs 205 pounds on fight night, and an average LHW weighs 225 on fight night
% difference between WW and MW = (205 - 190)/190 * 100 = 7.89%
% difference between MW and LHW = (225 - 205)/205 * 100 = 9.76%
% difference between (JJ @225) and DC = (248 - 225)/225 * 100 = 10.22%
% difference between (JJ @230) and DC = (248 - 230)/230 * 100 = 7.83%
Clearly you can see that even if you consider JJ as an average sized LHW the % difference between him and DC is only +0.46% more than between a MW and LHW.
However, if we assume JJ is a bigger than average LHW (ie + 5 pounds bigger) then the % difference between him and DC is even less than the difference between a WW and MW.
