Too late to edit: it looks like people are reading my comments as obliquely questioning 'waster's credentials. I can see how one could read my comments that way and given how conversations on the internet can go, how one may believe that to be the case; but that's really not my intent. If I took issue with their findings, I'd come out and say so. I'm just interested in finding out more where their coming from.
