I dont think ND takes into consideration how much more ronnie weighed than dorian, I don't think he scales the pictures right taking bodyweight into consideration
just my two cents
Well that's all depends on the year and the weight doesn't mean much if it's not backed by the conditioning.
Dorian 1995 was 260lbs , Ronnie 1998 was 249lbs , 1999 257lbs , 2000 , 264lbs , 2001 I believe he was 264lbs at the Olympia and 247lbs at the Arnold Classic , 2002 he was really down in size
Dorian was 260lbs will being hard as nails and arid as the desert , Ronnie was 264 in 2000 but soft & holding some water
the above pics were NOT scaled for accuracy just two similar poses , I tried my hand at scaled it's it's next to impossible to get it right so I don't even try anymore
