So we still don't know what determines the trajectory of the ball?
It may or may not use the lookup values 1-6 for being off center.  However, at this point we have no idea if a 03 is any different than a 06.

Some theories (yet to be tested) are that they may be used to skew the probability of trajectory.  Or maybe they are used to determine the hook/slice of the ball?

I've always assumed that trajectory was determined solely by the ball's position relative to the bat's position "vertically" (front or back of the batter's box), although I don't think anyone has gone into the calculations (for example, to see if you get any more power pulling the ball).  It would be interesting to know whether horizontal position affected hook or slice - I think of the bad slices to the opposite field coming off the end of the bat, but I don't really know that.

I should have clarified.
When I say "trajectory" I was talking up or down.

I do believe that what direction (left or right) the ball is hit is determined by how far ahead or behind the pitch you are.
