Allright, I'll prove that by myself. It's just late and I'm a bit lazy:

Too bad unlike your opinion, the book is valid and canon. If it doesn't contradict what's on screen, it's valid, and most of the duel is completely valid. You making up shit, which is contradicted on screen, however, is as far from valid as one can possible be. Like this:He didn't overwhelm anybody in sabers, he knocked them both off balance with the Force, just like in the novel. He didn't outmaneuver them and constantly kept himself away from both in combat.
You're wrong:
OBI-WAN and ANAKIN move toward DOOKU.
OBI-WAN: You won't get away this time, Dooku.
OBI-WAN and ANAKIN charge COUNT DOOKU. A great sword fight ensues.
They don't pretend to be less skilled at that point. In a novel, when they did, it was stated to look pathetic, not "great".
COUNT DOOKU: I've been looking forward to this.
ANAKIN: My powers have doubled since the last time we met, Count.
COUNT DOOKU: Good. Twice the pride, double the fall.
DOOKU lunges at the JEDI and they fall back . . .
COUNT DOOKU: (continuing) Your moves are clumsy, Kenobi . . . too predictable. You'll have to do better.
As the battle proceeds, OBI-WAN and COUNT DOOKU are tired. ANAKIN is stronger as he becomes angry. ANAKIN continues to drive the attack on DOOKU. COUNT DOOKU throws OBI-WAN back using the Force.
ANAKIN and COUNT DOOKU move up the stairs.
Red parts were cut off. Sad, but those parts might suggest that They were holding back.
Yellow part might be true, some parts were cut off, it's not likely that Dooku and Kenobi were as tired as it's stated. I might be wrong here though.
As they reach the upper landing of the General's Quarters, ANAKIN leaps over COUNT DOOKU. OBI-WAN reaches the top of the stairs, destroying TWO SUPER BATTLE DROIDS.LACK OF A LITTLE PART COUNT DOOKU holds OBI-WAN in the air using the Force as he turns and kicks ANAKIN out of frame. OBI-WAN is choking.
ANAKIN hits the archway.
DOOKU sends OBI-WAN flying. The Jedi tumbles to the lower level unconscious. COUNT DOOKU spins around again and, using the Force, causes a section of the balcony to drop onto OBI-WAN. ANAKIN spins and kicks COUNT DOOKU, sending him over the balcony. ANAKIN Jumps, following him down to the main floor. COUNT DOOKU and ANAKIN continue the fight.
Lacking part:

1:44 They clashed their sabers, Dooku overhelmes/outmanuveres them and throw them off-balance
So, there is no part on screen that would suggest that there were holding back. So it's less possile that any of them was that tired.
There wasn't also any single part, when Kenobi dueled Dooku alone, so Dooku couldn't even try to break Kenobi's defense, he has no time for that.
And, a little offtop - could you bring me quote, that Dooku used all of his energy to defeat Kenobi? Or, perhaps you mean "he used all of his remaining enrgy" (which was reduced mostly by Skywaler's attacks)? That's a great difference
