On the right track with jiggle analysis: analyzing bullet average speed given the Mannlicher-Carcano’s muzzle velocity against air resistance, real-world speed-of-sound given the air temperature and other atmospheric conditions, and the reaction time of a 58-year-old man with vertigo. But we’ve gleaned all we can in that regard from the Zapruder film.
The Final Truth, for the first time anywhere, performs jiggle analyses on Bell, Towner, Dorman and a fourth film. Then using triangulation, the book fixes the time and place of the first shot.
Yet this jiggle analysis only confirms results already demonstrated by other means in The Final Truth.
