You're all over the place Dan, you show three Agents in Altgens6 who all look over their right shoulders looking for a sniper and who were all obviously at that point in time reacting to Kennedy showing signs of being shot and one describes the sounds at that later time in the plural "fireworks"!
Zapruder who was filming at a point not that much further away would have heard the same sounds or do you think that an additional ten or twenty yards would muffle the sounds?

You're all over the place DanReporting Sitzman's specific observation about the noise level of the shots at Zapruder's position, and her lack of reaction to them, is hardly "all over the place".
On the other hand, John, your own posts require a bit of clarification.
You posted the following:
Another factor to consider is after hearing a shot at approximately Z160, Connally quickly turns to the right.You then post the evidence for camera "jiggle". However, your jiggle analysis appears to be for shots around z222/z223, z312/z313 and
z150/z151So which is it- a first shot miss "at approximately z160" or at z150/z151?
Whichever it is,in the scenario you're proposing, the assassin has watched the limo turn from Main onto Houston, travel down Houston, turn left onto Elm Street, travel down Elm Street and as soon as the limo goes behind the oak tree, the assassin has decided to take the first shot. The very first moment the limo is obscured is the moment the assassin has decided is the perfect time to open fire!
In his WC testimony, Ronald Fischer makes the following point about the man sat in the Sniper's Nest seconds before the motorcade reaches Dealey Plaza:
"And I looked up and I watched the man for, oh, I'd say, 10 or 15 seconds. It was until the first car came around the corner of Houston and Main. And, then, when that car did come around the corner, I took my attention off of the man in the window and started watching the parade. The man held my attention for 10 or 15 seconds, because he appeared uncomfortable for one, and, secondly, he wasn't watching-uh---he didn't look like he was watching for the parade. He looked like he was looking down toward the Trinity River and the triple underpass down at the end-toward the end of Ell Street. And--uh--all the time I watched him, he never moved his head, he never-he never moved anything. Just was there transfixed."There could hardly be a better description of an assassin "visualising" the kill zone.
This is general view the assassin would've had as he stared "transfixed" at the kill zone.
To imagine he wasn't aware of the oak tree is a non-starter.
The assassin can see that the best shot is to be taken as the limo clears the oak tree and is in the open road beyond.
I have done a serious amount of research on the specific topic of when the first shot was fired ["The First Shot" thread]
I have collected a mountain of evidence which demonstrates that the first shot was taken around z222/z223 and is the shot that caused JFK's arms to fly towards his throat as seen in the Z-film.
You should trust me on this one John.
