A little from the other side:

Newcomb and Perry had some of it figured out.

Start by replacing their 10ft/21 frames with 10.2ft/21frames

Tony Krome, are there some tire measurements we should release?

Below is an excerpt from Newcomb and Perry's book "Murder From Within"

Apply simple math (if it disinterests you I understand, but I think you'll be greatly missing out) to the previous posting:

10.2ft/21frames = .48ft per frame x 18.3 frames(1sec) = 8.78ft per sec/1.47(1mph) = 5.98mph

Parameters being (+/-) .3frame, because of full frame(18fps) vs partial frame (18.3fps) count

The graphic below is an excerpt from what I provided Tony.

The scale is 1" = 10ft so each individual line is 1.25ft.

When I originally sent him the plotting results, I used 1.875ft as the distanced travel, but 1.875 was reflective of the individual measuring lines.

Hence the reason that equation is in red type.

So, 5.3mph(shorter frame span) vs 5.98mph so far.

Fairly close, and it will get tighter.

I don't want to dwell on this area too much, but for a little context, I have to with a few posts.

There should have been no reason for creating TWO versions of CE884, and yet, here's an excerpt from the graph below.

The limo speed combined, using both CE884 documents equals the limo speed set forth by Newcomb/Perry using the distance the WC used(10.2ft) to move West's plotting of a shot at extant z207/208 down to station# 381.3 = extant z218 approx,(behind the StemmonsSign)  

Remove the .9ft BS distance entry, and combine the total frame span involved from both documents or in essence, z161-z171 =10 frames.

That span puts us fairly close to (at the least) the eleven surmised by Newcomb/Perry.

The following is from Tom Purvis and his discussion with Robert West regarding the limo angular change relating to the CE884 entries from the previous post.

For use as a reference:

2.24mph = .18ft per frame

3.74mph = .30ft per frame

5.98mph = .48ft per frame

3.74mph = .30ft per frame

5.98mph = .48ft per frame

 

2.34ft/5.5frames = 5.3mph from graphic above

2.34ft + .30ft per frame(3.74mph)= 2.64ft

2.64ft/5.5frames =.48ft per frame = 5.98mph

or a little more than 1/2 frame removed will yield the same result.

2.34ft/4.87frames = .48ft per frame

I guess my parameter should be  +/- 1 frame instead of .3frame.

The excerpt is from the Clay Shaw trial. The witness is Robert West. He is the surveyor hired to handle the survey work for the WC and all the other official reenactments. I have added the graphic with the dot path connected vs a straight line path, beginning from where the bogus limo speed entry at z161/168 begins, to approx extant z225/226.

If you read West's responses, please ask yourself why there are objections.

Then, take a look at the graphic and ask yourself if there is a lateral angle that is created, connecting the dots.

I've added back what I purposely left out from the original plat, plus the angle/lines at which the dots connect from z208-231.

If you connect the dots from z231-z313(not shown) it is a straight line.

Back to Newcomb/Perry:

Credit to Tony Krome for directing me to this photo: https://emuseum.jfk.org/objects/29149/black-and-white-photograph-of-fbi-reenactment-of-assassinati

He started the following conversation(below)with astute observations of the chalked tire.

It's a fairly quick read and I'll follow up with the Newcomb/Perry support in the next post.

Copied from the last entry in the previous post pertaining to the tire chalk marks:

"My guess would be, since one full tire rotation equals 7.4ft and z207 is halfway between z222/240 while CE884 lists the z207-222 span at 14.8ft traveled which is exactly twice the 7.4ft rotation amount, the speed from z207-z222 according to the chalk marks would be:

18/15 = 1.2x 7.4ft = 8.88ft per sec / 1.47 = 6.04mph"

 

Newcomb/Perry expanded below, from the quote in red above by .0057

The difference between .48ft per frame and .4857ft per frame

10.2ft/21frames = .4857ft per frame x 18.3fps = 8.888ft per sec /1.47 = 6.046mph

That's a match between chalked tire and Newcomb/Perry.

Ok,I haven't read the whole thread,I just came to the end.

Is there any xxxxery going on?

After you listen to Dino for less than a minute, imagine on the plat above where the limo started veering leftward.

The area that needed fixing was the StemmonsSign, etc.

Why?

" DPD James Chaney (one of the four Presidential motorcyclists)---stated that the Presidential limousine stopped momentarily after the first shot (according to the testimony of Mark Lane; corroborated by the testimony of fellow DPD motorycle officer Marion Baker: Chaney told him that "…at the time, after the shooting, from the time the first shot rang out, the car stopped completely, pulled to the left and stopped."

TSBD Supervisor Roy Truly---after the first shot "…I saw the President's car swerve to the left and stop(Extant Z135?) somewhere down in the area…[it stopped] for a second or two or something like that…I just saw it stop." [3 H 221, 266];

Dallas Morning News reporter Mary Woodward (Pillsworth)---"…Instead of speeding up the car, the car came to a halt."; she saw the President's car come to a halt after the first shot.

"DPD D.V. Harkness---". . . I saw the first shot and the President's car slow[ed] down to almost a stop…I heard the first shot and saw the President's car almost come to a stop and some of the agents [were] piling on the car." [6 H 309];

Delete (Extant135) I added that

And, since Newcomb/Perry arrived at frames missing where the WC melded two shots, one being a 10.2ft adjustment behind the StemmonsSign, while the tire chalking photo supports the reduced speed and/or limo stop as the plat plots a leftward moving limo behind the sign, it's no wonder Brehm might have conflated the events just a slight bit with regards to when the limo traveled 10-12ft.

The last time I checked, 10.2ft would be between that estimation.

Charles Brehm (on south side of Elm Street, close to the President at the start of the shooting), November 24, 1963: “Brehm expressed his opinion that between the first and third shots, the President’s car only seemed to move some 10 or 12 feet. It seemed to him that the automobile almost came to a halt after the first shot, but of this he is not certain.” [FBI re­ port: CE1425: 22H837]

In case you forgot, ballistically, JFK within the limo has to be in the correct physical location for the SBT magical mystery tour to succeed.
