1. What the hell are you rambling about? Yes he had to gather power, it doesn't matter how much he used of it. The point is if you need to gather power for something as basic as a push then certainly you'd need to do it to blow apart a freaking ship.
On the other hand all you have in support of max effort is this:
Besides, anything was possible. Dying, as he had thought once before, always seemed to bring out the best in him.
Which is f-ucking hilarious.
2. And then he contradicts it by saying anything he does leads him to defeat. And he didn't need to try to go for an indefensible position since anything he could've done would result in just that. Holy shit Nova 😬
3. Sorry, I should've remembered you like to discuss irrelevant shit.
4. Yeah...no. This doesn't sound like just drawing on the force at all: "He felt the dark side of the Force grow and gather." And what do you base it on that he didn't gather power in AotC?
Well it wasn't an opinion, but it was the deduction of an unreliable person. Since Dooku as you said wasn't in the room, all Kenobi saw that the ships moved easily, that doesn't mean Dooku didn't gather and exert much power to move them.
