I know you have to take everything Anakin says with a grain of a salt since he's an arrogant idiot, but could their be some truth to what he is saying. Star Wars isn't like Dragonball Z with power levels that can be increased with training, but after 3 years of war and fighting Ventress and Dooku himself, by the time he faces Dooku on the Invisible Hand; is it possible that his connection to the force is twice as strong and his skills as a swordsman are twice as good?
He says "Since the last time we met," which I believe was on Oba Diah. Assuming Anakin Skywalker grows by a factor of two between each meeting, and there are three or four meetings between Geonosis and Coruscant, he would be 8-16 times more powerful in ROTS than he was in AOTC.
C'mon guys; TCW came out long after RotS. I'm pretty sure that was the one line the creators couldn't create a BS excuse to explain why Anakin says my powers have doubled since the last time we met, Count. He's obviously referring just to AotC.
I'd be surprised if he hasn't grown by order(s) of magnitude, forget doubling. A difference of the order of one-shotting exists between the two versions.
Him doubling in power from end of DD( 6 months before ROTS) and ROTS is a more reasonable conclusion. A vast growth was stated for him, and coupled with his own words, not to mention, performances, yeah it makes sense that he doubled from DD to ROTS.
Arguing that he didn't even double from AoTC to ROTS makes no sense whatsoever.
Using Maths for measuring growth in power could be taken with a grain of salt, but saying that ROTS Anakin is twice as powerful as AOTC Anakin would be an understatement, so Anakin's claim about growing twice as powerful is a severe underestimation. I don't know about ROTS Anakin being twice as powerful as DD Anakin.
Basing on ROTS movie, ROTS script and Rise and fall of DV, Dooku had the upper hand over Anakin. Even after Obi-Wan's defeat, Anakin wasn't able to take an advantage over Dooku. But after he started to use his dark emotions, and reached clarity of mind's state, he nearly stomped Dooku.
Anakin's Djem So wasn't enough for Dooku, it's Stover's BS
