Wheen I first started doing pullups recently, I couldn't even do 5 sets of 5, by the 5th, I need help. Now I can do 10 reps with 15lbs. attached to me. Pullups use muscles in a way that you really need to do pullups to get better at pullups. I can do a lot more pullups palms facing me then palms away, but that probably because I have to use a narrow bar and I can't get a nice wide grip to get my lats into it.
I think saying how much someone should be able to bench depends on a lot. If you are 180 and 5'7" you probably have a lot moroe muscle mass then someone 180 and 6'3". The shorter guy doing his bodyweight is easy, where for the taller guy its much harder. If someone has very lowbody fat, they will weigh less and doing their bodyweight is easier(same muscle mass, less weight). I don't think bodyweight for any amount of reps is representitive of anything really, too many factors. Now if you are doing competitions, then strength for bodyweight matters, as you will be in a higher/harder weight class.
