Proof Rosemary Willis had started looking towards the TSBD by Z-145

I think you meant that she stopped filming before the first shot.  To figure out where JFK is on Elm St. all you need to do is see where the sightline from the camera through JFK extends to and then plot that sightline on a map of Dealey Plaza:

   The above would be perfect if Towner was looking through a monocular. And then she was panning too.

I think her camera had only one lens. She wasn't filming through binoculars. What does panning have to do with the position of JFK in the last frame?

If Tina Towner was right that the first shot occurred even 3 or 4 seconds after she stopped filming then there was no early first shot miss.

   Towner panning would impact the Line-Of-Sight (LOS). You're visual aid shows her LOS being straight lined.
    I agree. Not only was there, "...no early first shot miss", there was no early first shot period.

A frame is exposed for 1/40th of a second. If, during that 1/40th of a second the camera keeps the moving limo in the same position by panning, the background will be blurred and the limo will be sharp.   But in Towner’s last frame, the moving vehicles are blurred and the background is sharp, which means there was minimal panning of the camera. 



In any event, the movement of the car during the 25 ms exposure is less than 6 inches.
