If you are correct, that makes it even more unlikely that the first shot was at z222. You have her opposite JFK at about z198. She said "The car he was in was almost directly in front of where I was standing when I heard the first explosion". If she was right, that puts the first shot sound enough before z198 to give the impression that the car was not quite directly in front of her. If you subtract 1.5 frames to find the time the bullet hit, that would mean the bullet hit before z195.
A group of five witnesses to her right - Templin, Brandt, Newman, Burney and Dishong - unanimously agree that JFK had passed their position at the time of the first shot.
Westbrook's reported phrase, that the "car he was in was almost directly in front of where I was standing when I heard the first explosion", simply means that her position was close to the limo at the time of the first shot. It does not give us any information as to whether the limo had passed her position or not. You have chosen it to mean the limo had not yet reached her position. That's your choice. You do this in spite of the group of witnesses to her right who have the limo already past their position at the time of the first shot. Something that agrees with John Chism's claim that the limo was in front of him at the time of the first shot.
That you prefer your own twisted interpretation of a single piece of evidence to suit your own needs, over the mass of evidence contradicting you dead theory, isn't anything new.
