Well there is a constant inaccuracy in Star Wars power levels. They literally perform differently in every single fight. Yet Anakin has dominated Count Dooku in ROTS so I don't think Anakin's style being Dooku's kryptonite thing is enough to justify his loss. Windu is the second most powerful jedi of the order during ROTS and GL himself stated that you have to be Windu's or Yoda's level to keep up with Sidious in a duel. Since it is clear that there is a gap of power level between Vader and Anakin, I reached the conclusion that Widnu>Vader>Anakin>Dooku would be the most logical way to place them.
There's a hitch in your theory, that is every canon source has stated that Dooku is equal to Mace, if anything it edges towards the Count being stronger.
I haven't really heard a sound argument for Windu gaining any larger powerboost than Dooku would have from the DS boost. Also Dark Rendezvous which occurs mere months before ROTS states the Count and Mace are equals.
And Sidious is a nightmare for a fighter like Dooku for the same reason Zonakin is. He's got raw power and speed out the wazzuu and unlike Skywalker he's got the mastery to back it up.
Mace on the otherhand is equipped with the form to take that raw power and turn it against him. Against someone like Dooku however who isn't really a raw power fighter I think Vaapad's usefulness will be far less giving the advantage to the Count.
It's actually quite realistic. If you watch any combat sport, every fighter performs differently against different fighters. And A > B > C doesn't always work at all.
Plus every fighter will have their good and bad days.
Don't forget Dooku also dominated Anakin and Kenobi combined in ROTS. And Anakin was unable to overpower Obi-Wan in ROTS, who Dooku utterly stomped.
It also seems TCW makers seem to think Windu and Dooku are about equals. Since they had Windu stalemate Talzin, in an episode that was originally supposed to feature Dooku as the villain. And the reason they switched from Dooku to Talzin was nothing to do with Dooku's power level being inable to compete with and stalemate Windu. But to do with the Villain's motives in that episode being more suitable for Talzin. The fight was also much longer, but had to be cut down to fit in the episode.
Also Sidious will be shown in SOD to be flat out more powerful than Talzin who Mace was stalemating. Plus there's the fact that Maul was able to engage Windu and another Council member together. The idea of Maul engaging Sidious plus another Council Level Jedi together is frankly out of the question.
So yeah A > B > C doesn't work at all. Sidious is far more powerful than Mace, but for whatever reason (Vapaad is as good as explanation as any), Mace can compete with Sidious.
Also remember Lucas said you have to be Mace or Yoda to compete with Sidious. But he never said it was a 3 way triangle. I.e. he never said you have to be Yoda or Sidious to compete with Mace.
