Think you're completely contradicting yourself there.
For him to be doing it for free in the first place shows a leaning, whether you like that or not.
Anyway, it's irrelevant.
Something that struck me through the whole series that nobody who submitted a sample actually saw where the sample came from which doesn't bode well for anything.
Even Smeja who from day one was saying that he wasn't 100% that the steak came from what he shot.
As per usual, I'm disappointed with the researchers > samples involved in this more than the show or subject although I do understand how difficult it use be to obtain any kind of sampe which is why people jump the gun and get excited regarding samples that in truth, they have no idea what they are or where they come from in the first place.
