Jules in the pics is at about 9-10% and 175, putting him at a smaller LBM than I am in the Avatar... there is no way on this earth I am carrying more muscle in that pic than he was.
How many time do you see people saying they are 15% bf and 220lbs ??? thats a LBM of 187lbs which is pretty close to natural potential for someone of average height. for example Clarence Ross (Mr American 1945) was 5'10" and 185lbs at about 10% body fat...
Moral of the story, dont worry about what bf% you are at, just pick a way of testing it and make sure it is moving in the right direction, other wise you are gonna go mad thinking why you dont look like Mr America when you have 'apparently' got more LBM than them AND a lower body fat

Biggest problem is everyone does a "skin fold" test. This leaves out all the inner fat and only calculates the outer-just below the shin fat. This ends up being counted as LBM when it is fat. Here is a good read on it. Get in touch with your inner fat - Telegraph
