Where can i find footage showing that the distance between the limo & the follow-up car diminishes?
Where can i find the listed measurements?
The Nix Muchmore Bronson footages show the gap (ie the 2 limos are in the same frame) starting at almost Z312. No good to me.
Likewize any footage or photo before say Z218 is of little use to me.
The critical period is say Z280 to Z300.
Marjan, I have actually been working on some of these measurements and calculations for a long time. I actually did extensive work several years ago and I am just now finding time to work on it some more and coax the data to be presentable in an understandable and scientific way. I want to publish the data along with ways in which someone can repeat it, verify it, scrutinize it, and critique it.
I can share some of it with you on a private basis, but I am not ready to do so openly until I'm ready. It answers this and several other things. But spoiler alert: the evidence shows the limo slows and that the Zapruder film appears to be consistent with a real, uncut film, at least in the portions I can study.
This invitation is open to anyone on the forum who wants to see the data rather than some guessing and supposition.
I am primarily researching an as-yet unknown feature of the Zapruder film, but one of the side benefits is that is can be used to calculate the limo motion pretty accurately ... or particularly, find anomalies in the motion of the limo. It could, conceivably, find anomalies in the Z-film itself, if there are any.
My research is somewhat like the work of Alvarez on the limo, but, unlike him, I show my work ... and, as other researchers have postulated, he was not completely accurate. If you look at his *HSCA report, Figure 7, you can tell without processing the data that he's cooking the numbers. (Watch his inaccurate use of the word "exactly" in the same sentence as the not-so-exact "few.") The epitome of absurdity in Alvarez's work on the limo stop is his Figure 7 caption: "Individual measurements are accurate to about +/- 4 inches." Yeah, ok, whatever. Meanwhile, the same graph has "~12 mph" and "~10 feet" which sounds pretty approximate! What hubris. He did not do anywhere near the research to come up with +/- 4 inch accuracy. That's ridiculous.
