Holland's "Lost Bullet" would have come (sic) as Zapruder was filming the Limo making the turn onto Elm St. Except this "Lost Bullet" was Not fired from the sniper's nest. Different bullet, 2nd shooter.
Storing,
1) Why are you so obsessed with Holland's first-shot-at-hypothetical-"Z-107" theory? (Regardless, at "Z-107" the limo had already finished its turn.)
2) Aren't you familiar with Roselle's and Scearce's 2020 first-shot-at-hypothetical-"Z-124" theory?
3) Are you trying to say that the Zapruder film was edited by the bad guys to hide the "fact" that the first, missing-everything, shot was fired by "the 2nd shooter" from a different location?
4) How many bad guys and really, really bad gals do you figure were involved, altogether, in the planning, the "patsy-ing," the shooting, the escaping, and the all-important cover up?
5) Just a few, or oodles and gobs?
