Sorry, but anecdotal evidence doesn't prove anything.It's true that even abundant empirical evidence is not by itself proof. But this is a hobbyist's group, so this wouldn't be the place to expect participants to be conducting the kind of scientific testing you probably prefer. Regardless, it's simply false to claim that "there is no evidence." There's tons of it. If it doesn't suit you, you're free to go collect your own. If you do, please share the results with us.
