What Miroslav started with is borderline "nothing at all should be tested or at least can not be trusted" and that is a subject I won't touch and is out of place here.
Oh...ok...so now you know what I meant to say even if I didn't say it.
My point was that there are tests that have analytical results...but the thing you are looking for, "how many people can hear a difference" is never going to be analytical...only subjective. IOW...how do we know that someone does or doesn't heart a difference, or what that difference is...?
Again...what is it that you're trying to drill down to? Just cut to the chase, it will help the discussion get to a point.
