Some initial elements of the golden ratio.

If one looks hard enough at the elements of a golden ratio, those elements may eventually revolve around a golden ?

And, might just dictate where the WC needed to start there data input for extant z frames.

Try some simple addition using the elements.

P.S. What shape is created with a rise, run and hypotenuse?

       That should answer the first question in this post.

Now you're mixing math and Heroin    B)

Side a = window sill:490.7 -  limo elevation:429.25 = 61.45' @ the window sill.

CE887 shows them placing the muzzle 10" above the sill...

They claim they made the 10" limo height adjustment, but they did not... moving the muzzle up 10" changes the angles to the limo and the stand-in, it does not accurately change the CE884 measurements which are to the stand-in.  The correct method would be to align the stand-in's chalk mark to the window sill, THEN raise the rifle 10" and re-establish where JFK would have been... 15.25 feet further down Elm.

Side b = distance from elevation 429.25 supposedly at station 3+29.2, back to the base of the TSBD which is the 3rd side of the triangle requiring knowledge of the other 2.

Side c = 137.4'

a squared = 3776.1025
c squared = 18878.76

sq root of (18878.76 - 3776) = 122.89'

right angle triangle : 122.89 x 137.4 x 61.45   So what's 122.89 feet from 6.5feety from the TSBD corner?  

The rear bumper of the limo at WEST's path z171 - which, as Chris shows = 3+34.94 
while on the FBI path this crosses at the 171-dot created by Shaneyfelt 1 foot south of extant z166.
Then we get the 3 frames(168-171) = 9" changed in CE884 to 5 frames(161-166) for the same distance.

"Levers" that can be changed which affect the conclusions of the surveying:

  • Rear of limo v JFK location
  • 10" height diff
  • Robert WEST path versus Shaneyfelt's FBI path
  • Actual height of JFK's head
  • distance from the true TSBD corner
  • Station C and Position A
  • Height of Zapruder and pedestal
  • etc.....

Concrete support for David's summary.

Survey for Station# 3+29.2

Elev 491.53(Rifle barrel end) - 490.7(window sill) = .83ft = 10 inches

David's right triangle height = 61.45ft - Survey says 62.28ft difference = .83ft = 10 inches

P.S. I prefer hero ine

According to the elevations I saw the base of TSBD is at elevation 430.2 with the sill at 490.7 = 60.5, not 60.25.
According to the WEST plat where 1"=20' the 2 measurements are: 490.9 & 430.2 leaving 60.7' from base to sill

That's 60.7 - 60.25 = .45' = 5.4 inches higher than WEST's measurement.  Keeping all things constant, the extra .45' moves JFK forward .45 * 18.3 = 8.235'

431.28 - 2.03 = 429.25 = z161 on CE884 which originally was surveyed at z168 (designated by Shaneyfelt, not WEST.  
WEST simply surveyed the spot he was told by the FBI was 168.   171 was then placed 9" further down Elm.  

This charade was born between Station C the corner of the TSBD, the sill of the TSBD 6th floor East window, thru Position A and prior to the frame we know of as z161.

Z156-157-158 is the beginning of this transition with a break in the film.  The next "break" occurs related to a shot at/around 207.
Frames are missing from 303-304 and 316-317.

FWIW
Chris, do you see any "adjustments" made in the WEST data for the 10" difference for 168?  I don't 
Where does the 60.25' come from when the plats say something else?

On one of the Purvis pages he shows the line art legend which was "redone" in June 1964...  490.9 and 430.2 are listed

What say you my friend?

No adjustments in the West data for a 10" difference.

60.25ft is the measurement to the theodolite (standard practice), which was 2.03ft higher, than the 3.27ft above the ground. 

Hence the difference between 60.25 and 62.28ft

The H.I. upper left, stands for "Height of Instrument"

Street elev at Station# 2+50 = 429.7.

TSBD building base at Station# 2+50 = elev 430.2

Difference = .5ft = the curb

Difference between window sill elev (490.9) - (430.2) TSBD building base = 60.7ft

       That should answer the first question in this post.

 

 

Getting back to my hallucinogenic math, I find it helps to use online calculators.

If I run a calculation on that hypotenuse (137.44ft to be exact) for frame 161-Station# 3+29.2, the run is 84.94ft and the rise is 108.04ft.

I suggest referring back to the golden ratio elements to see if 84.94ft is one of them.

The only entry missing in the online calculator result is the angle that was used. Purposely.

So the Egyptians killed JFK???  :blink:

90 - 38.173 = 51.827 degrees at the window down to the target...  

The triangle you describe at Z161:  
hyp = rifle muzzle to target = 137.44' 
side a = target to TSBD base = 108.05'
side b = TSBD base to rifle = 85'

Except side B, the distance to the TSBD window from the base, was not 85' but only 61'

Isn't the RUN 108' and the RISE is 85'... IOW the height of the TSBD??

108 feet is the distance from TSBD base to rear bumper at WEST's 161.

Or,

The golden ratio (1.618) removed from the hypotenuse of z161(137.44ft) 

Sorry about that.

The hypotenuse of z161(137.44ft) / the golden ratio (1.618) = 84.94ft = the street distance from station# 2+50 (rifle end in snipers nest)  to the plotted location of "JFK within limo" via the WEST path (Station# 3+34.94) on the same Z LOS labeled as z171 via Shaneyfelt's path.

Is the 137.44 a hypotenuse on the street or from the window?  Since the street distance does not meet up with the 84.94' line taking us to JFK at the filmed location designated frame 166 on the R.WEST path.  (and as you show,  FBI's 168/171 winds up further up Elm than the film of these frames shows.

When there is a distinct conflict between what the film shows and what the FBI says... why would they not default to the film unless the film did not represent the info as desired?

The 137.4 ft hypotenuse (converted to 137.44 for true golden ratio equation) is taken from the window via the z168 survey document supplied earlier.

The Giza triangle forms on the street.  

I previously pointed out what station# (on the West path) I thought would dictate a vertex (endpoint) for Giza.

You have a 50/50 chance to select from this graphic as your other vertexes.

When there is a distinct conflict between what the film shows and what the FBI says... why would they not default to the film unless the film did not represent the info as desired?

They did TRY to default to the extant film with the public version release of CE884 which assigns z166 to station# 3+30.1,this, when used with the background lightpost as a landmark measuring stick and "JFK within the limo" as the mark on Shaneyfelt's path, gets them as close as they can get.

Working backwards from there, the problem with this scenario being, the limo traveled more than .9ft in 5frames(z166-161). There has to be accountability for the unresolved distance. Just like there has to be accountability for the 10" vertical drop = 15.25ft horizontal run. 

So then what do we get, a final CE884 (June, 1964 WC plat) with that same Shaneyfelt path previously described and a frame number assignment of z171, which, when surveying frame numbers according to the extant film (using the obvious landmark lightpost in the background to plot JFK's location) somehow amounts to a five frame difference (z166-z171) for the same location.
