Vapaad's superconducting loop isn't circumstantial. The boost Mace got from the revelation that Sidious was a sith was still something he could draw on even after overcoming his emotional turmoil.
That this was some sort of temporal amp is utterly unsupported. Untill someone can provide actual evidence here, anyone arguing that Mace's vapaad boost was circumstantial is perpetuating unsubstantiated nonsense.
