Haha. the second article you link is the only one that looks at different proportions of macronutrients in recovery drinks and it concludes that it doesn't really matter. And sadly, none of the studies look at any kind of performance outcome, which quite honestly is the only thing that matters. Personally, I'd draw no conclusion from any of those articles as to what I should drink, but I'll bet what I'm doing ultimately derives from studies like this.

Good thing my recovery drinks are tasty and that I'd drink them even if I weren't trying to recover.
