Maybe we can settle this debate by reference to the lane markers. In this frame from the 1963 Secret Service film, JFK's back is even with the end of the lane markers:
Here is CE882, the scale map of Dealey Plaza showing the lane markers on which I have shown the position of JFK when he is in the position of being even with the ends of the lane markers:

On this, I have shown the sight line from Zapruder to JFK and extended it to the right where it intersects with the very end of the curved concrete wall around the end of the reflecting pool.
So to determine the zframe that this corresponds to, we simply look for the frame in which JFK aligns with the end of that concrete wall. It appears to be z196:

I would have to say it would be well before this position. JFK has been in the clear for almost a car length, say 15-20 feet. Why would the shooter wait at all? I would suggest that, since JFK was visible while passing under the outer oak tree branches, the shooter could easily have pulled the trigger as soon as he was clear and did not have to wait at all. He could have fired even a bit earlier than that while JFK was here but still quite visible:

Maybe we can settle this debate by reference to the lane markersRest assured, this debate was settled quite some time ago.
It was settled the day the FBI did it's reconstruction.
At z193 JFK is still passing beneath the oak tree from the SN PoV.
It doesn't matter if you don't accept that. It really doesn't matter at all.
It doesn't matter that all your arguments have been destroyed over and over again.
It doesn't matter how deep in denial you are.
None of it matters.
