Yes it is splitting hairs, but i definitely remember a youtube of Tina saying that she woznt sure whether she stopped filming just before the first shot or just after. I think it woz in the context of talking to max Holland, in which case Tina might have said that just to make Max happy, i can understand that.
But my forensic analysis says that she heard shot1 at T141 & Tina stopped filming at T142.
Oswald shot at T137.
The slug hit at T138.
The sound hit at T139.
The ear part of Tina's brain told the main part of Tina's brain at T141.
Tina stopped filming at T142.
At 1:00 Tina says that the first shot was at about when she stopped filming.
But i still have not been able to find the footage where she says that she wasn’t sure whether the first shot was before or after she stopped filming.
Anyhow, i say that the first shot was at Z111, slug ricocheted at Z112, sound hit JFK at Z113.
Holland said that the first shot was at i think Z103.
Anyhow, me & Holland agree exactly re the pozzy of JFK at the first shot, his back was in line with the arm holding the overhead signals, ie the line from the Carcano to signal arm to JFK's back.
At 2:04 a guy says that there was a hole in the traffic signal -- no, that hole is a gap in the backboard -- the guy that owns that traffic signal (Christopher) has told us that there is no bullet hole.
