Oberkommando:
We should NOT (as you did) compare an "average" person training in Pavel's methods with a serious bodybuilder. Even with the latter's inefficiency, if he has more training, he may exceed the "average" person with very little volume of training (obviously).
As you know, that wouldn't be a fair comparison. We should compare two average human beings spending similar amount of time training in Pavel's methods and "bodybuilding" methods and see who comes out "better," especially in regards to "combat conditioning." In that case, it will be pretty clear who the winner would be.
And, yes, given all the other variable constant (including the same level of skills), GENERALLY a stronger (not necessarily heavier) fighter will beat a weaker partner. However, the other variable will not always be constant when there is an absolute strength disparity. There will also be disparities in weight, cardio-vascular conditioning and such (not to mention SKILL).
In other words, "bigger is better" only applies to a certain extent. A 200 pounder may indeed pound a 120 pounder in boxing. But will a 500 pounder slob beat a well-conditioned 225 pounder? Probably not. Weight IS a factor, but one among several.
BTW, Bruce Lee is NOT my ideal. What my ideal is whatever allows me to approach the theoretical peak efficiency for fighting skills given my circumstances and in-born factors (including my genetic pre-dispositions).
I will say this. There is, in this country (USA), a certain love affair with the looks of an Arnold Schwartzenegger as the "ultimate fighter" body type. The reality is actually much different. In UFC and similar NHB contests, the fighters with "bodybuilder" body types have not done well in general.
Ken Shamrock is an interesting case. But, he made an extensive use of steroids. If you want to see a superbly conditioned fighting athelete look to his adopted brother Frank Shamrock or Egan Inoue (Enson Inoue's brother). They didn't takeup "bodybudiling" routine, let me tell you.
Sometimes, what I find really amusing is that some of the bodybuilding types around the gym I used to belong to would hulk around acting like tough guys. Some of these guys weighed about 225-275lb. (with huge muscles) and acted like they could crush little me (170-175lb. with moderate size muscles) Any of them who bothered to show up on the mat to wrestle with me ("that Jujitsu **** won't work on me") alway squealed like little girls when I submitted them (usually with an ankle lock or an arm lock). And I don't even use a full repertoire of my fighting techniques or weapons (like knives) on the mat.
Some of my immature friends still make remarks like "Wow, look at that big guy. I don't care what you study. You won't beat that guy in a fight." I always reply, "Maybe or maybe not, but whether I win or lose is NOT going to depend on how muscular he looks. It's going to depend on his level of "combat" traninig, his mentality, his conditioning and, yes, his strength. There are other variable as well."
