But we're not. We're just showing you something that I told you about a couple of pages ago: for your theory to work, it must work for everyone. The moment you start making allowances for such and such, you've got yourself a sinking ship.
At the moment, we're just throwing your own arguments back at you with stupid examples, and the question,
"Does it work now?" The answer, of course, is no, so that means the reasoning/theory behing all of this must be flawed, at least in part.
I personnally have nothing against a kind of "unified theory of weak-Federer-era-ship", but it has to hold water when you use the same arguments to judge the other eras against, and I don't think you're ever going to manage that one...
