generally accepted advice isn't always right: I put on 17lbs of muscle in three months (Parris Island, SC). I was underweight at the time, and a teenager.
I did mention in my post that it doesn't apply to teenagers, although I should've been more explicit at that. Growing children can generally make tremendous progress, as can untrained novices.
Your post doesn't really refute my point anyways, because it's very hard to gain muscle and lose fat at the same time for adults. You're talking about one direction i.e. gaining muscle.
