Not starting this one with studies, just starting the conversation. Overall, there isn't particularly good info I've seen as to optimal BCAA ratios. Even more difficult though is beyond that determining dollar value. Just as the example, if 10g bcaas cost more than twice as much as whey, even if they provide more anabolic response than 10g of whey, do they provide more than 20g?
I'm willing to bet there aren't any studies at all that would look at the financial end, but there probably are some that do look at comparing different doses of different protein/AA sources. This like plenty of other things in the diet/nutrition world is of course based on who is going to pay for the study.
My own gut feeling is that going outside of the 2:1:1 - 4:1:1 range hits the point where going higher you may as well just get leucine. I need to look again at which aminos are the rate limiters in which processes to be sure as far as going to lower ratios. I've never seen any that were below 2:1:1.
So what does anyone else think?
