Would you care to elaborate on what, specifically, is flawed about meta analysis? I'd definitely be interested in a source on that 60% number and how that source arrived at a number that seems, on it's face, so incorrect.

I'd be curious to see if anyone has actually done a study on this, but to me this number actually seems quite low. I would guess that it would easily be 90+%.
