Dealing with the kinds of things that exist within our mind state, it matters very much what tense your laying down your scenario, because it can change the board quite drastically. Free will only exists in the present, so if your tense is backward-looking its imperceptible, the outcome will appear causal even though its not determinable by the most sophisticated forms of mental arithmetic ie. outcomes are not computed because they are manufactured (with a decision). This free will endorses options out of necessity, but where there was only one course of action conceivable the degree with which this option is endorsed is independent of the fact there was but one course possible.
Choice might look like the determinant factor in the outcome, but this is not so, because the rendering of the outcome is produced by an exercise of the will that we ourselves have first hand access to, it's free in all the ways your mental life is un-reigned in its powers. Choice is independent of the conviction bundled into a decision, that was the only point I wished to draw from my opening remarks, options aren't expression of differing wills one might elect, the plane on which we make decisions is infinite, its only the outcome that must conform to causal account because that's the point at which the infinite stuff of the mental immaterial plane meets the material world, but in any account must be included that infinite scope of the will which is not just mechanically forced to elect one of the options before it, it can do so with a particular measure of endorsement not to mention unpredictability.
