This flat-line distance equals JFK's position in extant zframe 207. If you look closely, it was labeled very lightly on the 1963SS/1964FBI plat.

There is a determination of a shot, via Time-Life, at extant z207 street location.
The WC CE884 zframes 207/208 has a rifle angle to JFK's head (3.27ft above the street) between 21degrees34minutes & 21degrees 50 minutes.
The SS plat shows a very similar angle (21.63=21degrees38minutes) which would land between the WC 207/208 span. Remember, the SS plotting of shot#1 was to the street, not to JFK's head height (3.27ft above pavement) at the head shot.
The plotting of the first shot on the SS plat would actually be closer to extant zframe 217 using CE884 as a measuring tool.
