I don't think so. I think that, by now, he somehow got used with his slow decline and he will not snap to embarassing levels anymore.
I think he was very, very close in the spring of 2009, after the AO selfinflicted humiliation and the IW+Miami combo but then the summer of 2009 taught him to be patient and to have the last laugh, I suppose.
One think I agree with. Fed is not as calm and composed as people waxing lirically over him make you want to believe. He's a Leo, so he has to have a fire temper. All his calm attitude is self imposed and learned not natural.
I'm a Leo, I was born 2 days (and countless years unfortunately) before him.
I'm kinda more like a Virgo though.
(I mean esp the obsession with cleanliness hence cleaning the toilets.
