Stemmons Freeway Sign damage?

[Glenn Nall]

has anyone seen William Orchard's take on the shots and the sign being damaged in Zapruder film: http://theshotsindealeyplaza.com/?page_id=156? any thoughts? (perhaps I should do a search in the forum...)

on this note, though, i'm reminded of something i thought the other day that i'd like to see:

I came across an exact sequence of shots (i think it was in Anthony Summers' book i was reading last month and subsequently lost on the subway halfway through it - aarrrgggghhh!!!) which made clear the difficulty in firing two shots from any bolt action so close together - something like 1.7 seconds between #'s 2 and 3...? does anyone have these times and does anyone know of a layout of Zframes chronologically timed to the known and possible other gunshots?

does that make any sense?
