I think people here are using a very weak definition of "know". If I know that I will X, then I will X. If it later turns out that I didn't X, then I did not actually know that I will X. That I will X is logically implied by anyone knowing that I will X.

I'm not sure how anyone could achieve actual knowledge of one's future actions, but I agree that there's little reason to deliberate over them if one does.

Often you know what your actions are going to be a split-second before you take them. After you have decided what to do but before the motor signals go out. That's the type of advance-knowledge I was considering.

The information isn't certain - but then NO information is certain.

NO information is certain.

Maybe.
