> I'd say that how much free will you exert is determined by how much your decisions are driven by your internal "me" state vs. the external influence.

I reckon this definition would be very difficult to formalise meaningfully. Going back to the thought experiment in the white room, it might be that my choice is strongly influenced by whether the walls are cream or vanilla. My choice might be influenced by whether a certain smell or noise happens to occur just before I decide. I have a constant stream of inputs flooding into my system, affecting my choice-making. Some of those inputs involve deliberate actions by other agents (e.g. Alice pressing a button) whilst others are simply the goings-on of the environment. I suspect it is impossible in the general case to conclude that a choice is driven more by internal state than external influence or vice versa.
