My understanding is that since FF powers itself once initiated, the Q would be infinite.

Presumably all above-breakeven fusion devices would be able to power themselves, and thus under that criterion have infinite Q. Perhaps I’m misunderstanding something here.
Well, a steady-state reactor requires continuous power input for magnets, etc., which pulsed does not. I don’t think Q applies well to pulsed generation, actually.
