The Transition Point Between Free Will and Ballistic Movement

There's some transition point where they change from being what we would describe as choice that we haven't got to free choice yet, but at least to choice. Once the action has been released, let's say, then I don't really have any free will because I can't stop it. And so there's a gradation from choice to determinism, a temporal gradation. It looks like there's a temporal gradient with regards to free will.
