He was a telekenisis instructor and was considered to be immensely powerful in the Force, as per various accolades, including Stover's description of him in the RotS novelization.
being a master of Makashi,
Not just a master - the master. His technical skills rival Kas'im's; they're up there among the greatest in the mythos.
occasionally owning lesser Jedi with force powers or in a lightsaber duel,
You think RotS Obi Wan is a "lesser" Jedi? Kenobi has been routinely described as one of the greatest duelists the Jedi Order has ever produced, and possibly the premier soresu master in history.
and not being as good as Yoda or Sidious.
He gives Yoda a good fight...that's far more than PoD Bane's ever done.
Furthermore, Dooku has an infinitely larger array of technical expertise than the inexperienced Bane, who was put on his ass in seconds by jar'kai...Dooku knows jar'kai (although realistically doesn't have two sabers here) and plenty of other lightsaber forms and combinations Bane would be unfamiliar with.

As for quantifying Anakin's feat in AotC...well, I'm too lazy to do the maths now, but we know that he hits an airspeeder at terminal velocity and deccelerates to zero vertically, while accelerating to however fast the airspeeder was moving horizontally, in a fraction of a second.
