Unfortunately for you, every single mechanical aspect of your Theory's first two shots has now been blown to smithereens. Not just by me, but Mytton, Nickerson and Collins. You have nothing; nada. But I'll show you what sort of fellow I am. I hope you get at least an orange in your sock.
Well, it hasn't really been tested, has it? All we have to go on is your and other's "expert" opinion. You have not done as I asked and given us a range that JFK's midline could have been from the right side of the car; you have not given us a range that JBC's midline could have been in relation to JFK's; you have not given us a range for the separation of JFK's neck from JBC's spine; and you have not given us a range for the angle that JBC is turned at z195. Until that is accurately determined, no one can say that the SN to JFK neck to JBC thigh trajectory was not possible. I suggest that it was quite possible from z190-200 or so. No one has proven otherwise.
If you're going to remain faithful to the shot pattern, think second shot Z240s (or maybe earlier, like one sec earlier).
That would require a first shot before Zapruder started filming. The evidence from multiple independent sources is that the first shot was after z186 and that it struck JFK.
It is not a matter of remaining faithful to the shot pattern. The 1.......2...3 shot pattern is based on multiple sources of real and independent evidence, not faith.
The SBT on the other hand, is based on the notion that this evidence is somehow not only wrong, but that there was something operating that caused over 40 witnesses (plus a host of others who simply described one shot and then two more shots) to get it wrong
the same way. Belief in such things is based on faith because there is certainly no evidence that that could occur, let alone that it did in this case.
