Started a draft response in my head and ended without publishing it because the post said it well enough, and a look at rabdphs produced the same effect, content that satisfies my urge to add to it by being complete enough on its own is rare and represents a particular kind of editorial completeness here.

Worth saying that the writing carries a particular kind of authority without making any explicit claims to it, and a stop at idealprotein extended that earned authority feeling, sites that demonstrate expertise through the quality of their explanations rather than by stating credentials are sites I trust most and this site has it.
