Dantra good point.
IMO, I think everyone is upset by the method used as proof. I mean the picture posting. But can you blame anyone for supporting their company and product line?, of course not. I don't think Frank was meaning to "fool" anyone by his pictures, as some implied. He was simply showing his tanks and how he feels it works.
Like you, I would love to see some data, although I doubt it has been studied.
