You're welcome. BTW, I'm not denying a majority of witnesses felt a certain way about the shot spanning and that they were honest in their reporting. I just don't think we should use such samplings from any shot-spanning group. It's a minor detail likely not measured in real time.
Which is where we disagree. I know you don't think the evidence is persuasive, (along with Betzner, Croft, Willis, the first shot-hit witnesses and first shot location witnesses) but I don't think it is unreasonable for someone to disagree with you. It appears that you do.
Also: "1.....2...3" looks pretty evenly-spaced to me.
5:3 (1.67:1) is evenly spaced? The spacing at 197, 272, 313 is more like 1.8:1
The Zapruder film shows she can't see Kennedy at all during the time of your first shot.
I don't know how you think she came to give evidence about seeing JFK slump and clutch at his throat, do you? It cannot be that she imagined seeing it but didn't and it is just a coincidence that this is what we actually see in the zfilm. The only other possibility is that someone told her to say this and the 14 year old girl lied to the Warren Commission about seeing it herself. Good luck finding evidence of that. So did all the other 20 people who reported the same thing lie the same way? Who would have an interest in saying this?
What else could that be? How about Johnson left arm reaching forward to grip or rest on the top of the front seat? The dark upright shape in front of Johnson's head is the back of Youngblood's head. Youngblood is turned to his right talking to Johnson who's leaning in to listen.
There is definitely something over the back of the front seat that is between Ladybird and LBJ:

You may notice that Johnson is very far to the car left and the space between Ladybird and LBJ is greater than that between Yarborough and Ladybird. Might that be because that large dark thing in between them happens to be SA Youngblood climbing over just like he said he did after the first shot?
Since Z271 has directional blur, how about we compare Z272 to a clearer frame?

There is a change of car angle between those two frames. Besides, the visor over the driver side is the one that was hit:

Lets look at the change in the driver's visor (and, while we are at it, in JBC's wrist) between z271 and 272:

Just that Hickey (and Kinney) can't possibly see to that area of the head at that moment. This is such an old chestnut.
Well, it is kind of amazing that JFK's hair actually did fly up without causing any damage just before the head shot, as Hickey said. He did not see what he said he saw and yet what he said he saw actually happened. You have not tried to explain that.
Wrong again. Connally actually moves across more of the width of the car before Z278 than after.
JBC moves. Watch the change in position of JBC from z271 to z279 relative to Nellie and Jackie who do not move at all. Now compare that to the position of Kellerman relative to Nellie and Greer. There is no change in position of Kellerman:
