Pat Speer produces a list of 44 eye-witnesses who saw JFK react to the first shot:
"For those reluctant to read through the plethora of statements and testimony recounted in the pages to follow, but who are nevertheless curious as to how I can feel so sure the first shot did not miss, I hereby offer a telling taste of the statements of every witness I could find who described the activities in the limousine during or just after the first shot. While some of these witnesses believed the first shot missed, they almost all believed Kennedy responded to the shot by leaning forward or jerking to his left, actions the Zapruder film reveals occurred only after he'd been hit. My conclusion that these witnesses were thereby describing Kennedy's actions between frames 190 and 224 of the Zapruder film is further confirmed by the fact that not one of these witnesses said the President continued waving and smiling to the crowd on his right after the first shot rang out. Common sense tells us that this should have been the impression of at least a few of these witnesses should they really have heard a shot at the time proposed by most "first shot miss" proponents, around frame 160 of the Zapruder film. But common sense, alas, is often ignored in favor of something more glamorous."
I won't reproduce the list in full. It can be seen here:

You don't have to scroll down far to the section entitled "The First Shot Miss Myth". This is proper evidence, not interpretation to suit one's needs.
I won't go through the whole list either. Some things near the top. Now this is Speer interpreting "Remote Viewers" accounts to associate the first shot with Z190-or-shortly after (he also links witnesses to the Z190-Z224 span for the first shot).
James Jarman (11-24-63 FBI report, CD5 p334-335) “He said that he heard a shot and then saw President Kennedy move his right hand up to his head."
Kennedy's right forearm rises up in the Z170s; it declines in the Z190s.
Ruth Smith (12-21-63 FBI interview, CD206 p.9) “She looked back toward President Kennedy’s car after the first shot and thinks he raised his hands to his face.”
Couldn't find much on this Ruth Smith. Don't know where she was standing or how many shots she heard.
Lillian Mooneyham (1-10-64 FBI report, 24H531) “Mrs. Mooneyham heard a gunshot and observed President Kennedy slump to the left of the seat of his car."
Well, hold on. Mrs Mooneyham was looking out Judge King's courtroom window with Jeanette Hooker and Rose Clark. The Old Red Courthouse is on the corner of Houston and Main. The women's view of the limousine was almost side-to, so Kennedy leaning towards Jackie isn't going to be very apparent. IMO, more likely she observed Kennedy's head nod in the Z170s. Of course she wasn't able to see Kennedy's full smile or know he was acknowledging the crowd. She heard a loud report and saw Kennedy make some movements.
Mrs. Hooker had an elevated side-on view of the limousine and the background behind it. "Mrs. HOOKER estimated that the President's car was almost to the R. L. THORNTON Freeway when she heard three gunshots." At Z190, relative to Hooker's view-line, the front of the car would be pass the sign.
Cecil Ault (1-10-64 FBI report, 24H534) “Mr. Ault heard three loud reports…Following the first shot Mr. Ault noted that President Kennedy appeared to raise up in his seat in the Presidential automobile and after the second shot the president slumped into his seat."
Maybe Cecil thought the President raising his arm and nodding his head in the Z170s meant something, because Kennedy doesn't "raise up" even for Speer's Z190-Z224 preference (the President's right arm is going down, if anything). Kennedy slumps down on taking the Z220s SBT shot, which Cecil's second shot account ("after the second shot the president slumped into his seat") matches. BTW, Cecil thought the first two shots were closer than the last two. Guess we can throw him under the bus.
