I'm KMC's Good Samaritan, so I'll help you all clean up the mess you've made.

This implies that Palpatine was controlling the duel... He certainly was not.
You mentioned earlier in this thread or in another that I make it my business to defend Sidious; after this little nugget (not to mention your own admission in the Favorite Characters thread that Windu is one of yours), we can assume you're exactly what you think I am; we just disagree on the character.
Your "implication" is irrelevant; the fact remains that the film, novelization, and screenplay depict Palpatine butchering two Jedi Masters before Mace can react and then taking on Fisto and Windu simultaneously; both of them together clearly aren't enough, Fisto is killed and, as dictated by the databank, the mighty Windu was forced back.
You read the novelization, correct? Then you know full well that it was only when Windu entrenched himself in Vaapad was he able to equal Sidious. And the source of Windu's power-up was Palpatine's own energy. So what can we assume? In terms of power, Windu's not even in Palpatine's league, and Palpatine was controlling the fight (initially, anyways) as per the databank. In fact, the screenplay also mentions that Palpatine forced Windu out onto the window, so take that for what it's worth.

There is no shame in conceding to me.
Stop pretending to be me; you make me seem like such a douche. In either case, Ares is correct: Palpatine was feigning weakness and was exaggerating his present condition as per the words of George Lucas. Objectively speaking, even without Lucas's acknowledgement, the film, novelization, and screenplay all but scream this fact: Palpatine communicated with Anakin via telepathy as Windu and the others were entering the office and as per the recent edition of the Star Wars Insider (which I flipped through at Barnes & Noble), Anakin perceived Windu to be the aggressor and Palpatine to be the victim. The whole thing was a set up to force Anakin's hand by putting him into a position where he had to make an impulsive decision against the Jedi.
As far as the duel itself is concerned, I've already established on other threads that Palpatine was clearly Windu's superior as the duel began. In fact, this duel is surprisingly similar in function to Anakin's final duel with Count Dooku. In both situations, the Sith Lords demonstrate superiority over their opponents; if Anakin had entered the fight equipped to kill the Count, then he and Kenobi would have been sufficient to slay the Sith. Instead, Dooku demonstrated power and skill in excess of Anakin's until Anakin entered a specific state of mind that enabled him to tap into his reservoirs of power to defeat Dooku.
Likewise, if Windu had entered that fight capable of kicking Sidious's ass, then he would have done so when he had three of his "celebrated swordsmen" teammates backing him up. Instead, that team was slaughtered rather casually and Windu was unable to defeat Palpatine even with Fisto in active assistance. Not to mention, of course, the fact that Windu was forced back into the main office.
No one disputes the fact that Windu won; but Palpatine definitely controlled the fight initially and it wasn't by superior skill or power that Windu defeated his enemy. The deficits of Vaapad were made manifest in both the novelization and screenplay; a second's distraction was enough for Palpatine to nearly kill Windu and it wasn't enough to defeat the Emperor outright.
Palpatine is far more powerful and possibly more skilled than Windu and there is zero indication that a 1v1 scenario would end the same way.
Wrapping it up, Vaapad is neither infallible nor a guaranteed technique to defeat dark siders. It is highly effective, sure, but Windu will be going head to head against a far more powerful Force user and an unrestrained psyche. He can win, of course, but I'm not persuaded by the evidence that he will.
