Lack of Freewill doesn't mean lack of choice

Although I suppose that’s only true if the state change is instantaneous, which might be what you meant. If it’s not, then at some point, we’d reach a situation where state changes could no longer be completed before the next switch happens. ‘0,5’ might then be a sensible answer if the ramp-up and ramp-down are symmetrical, although they probably wouldn’t be. But really, this is unrelated to the point I was making, which was really just to show that ‘determinate, but non-determined’ isn’t as impossible as one might think, and if it is believed to be, it’s not just free will that goes out of the window.
