I don't think that's what GP is saying. This report would be more believable and more objective if it would have other types of metrics than just self-reporting ones.

There is a kind of people that function by finding edge-cases, questioning the results and posing uneasy questions when presented with a situation. Some might call them "haters", or nit-pickers, but I think their way of thinking is useful to make sure we're not just being fed feel-good make-believe.
