  1. The public CE884 gives us this result for the first two entries. 5frames @ .9ft traveled = 18.3/5 = 3.66 x .9 = 3.294ft sec /1.47 = 2.24mph Missing six seconds in Dallas x 3.294ft per sec = 19.764ft http://educationforum.ipbhost.com/topic/22692-swan-song-math-rules/?do=findComment&comment=328146
  2. This will conclude the witness triangulation. Third car back would be the one with the door partially open in Hughes. I'd say this SS agent nailed it.
  3. Keyvan, I don't have the sprocket hole segment for that part of Towner. Never been able to locate it. All ears if someone does.
  4. Or this way, if it's any easier: Time difference for Towner's camera using Myer's 22.8fps and true fps of 18.3: 167/22.8 = 7.324 sec 167/18.3 = 9.125 sec Difference = 1.8 seconds x 18.3fps = 33frames 15 frame gap Towner End to Z beginning per Myers + 18 frames back from Towner End = Gif https://drive.google.com/file/d/0BwrExtVD005OVFNpeGRfYmpNYm8/view?usp=sharing
  5. Next Witness. https://drive.google.com/file/d/0BwrExtVD005ObmRiUHZGWEhYb1U/view?usp=sharing P.S. This all works quite well when taking into account the adjustment Myers used to create his multi-sync film project. Think of it this way. If I'm running on an oval race track and I'm on the outside lane while my competitor is running on the inside lane, who has to run farther around the turn? Take that distance difference, subtract it from where you see the limo start on the extant zfilm. Between that span is where you'll find the witnesses placing the first shot. Now realize that Towner's camera shot at 18.3fps (that's a 8mm camera) not the BS 22.8fps that Myers used and you'll understand how the time element was adjusted to sync with the distance difference. Then realize, these people thought the noise came from the TSBD 6th floor, instead of its true origin.
  6. LOS from Euins through "JFK within the limo" to background structure. Station# 2+99 = extant z133
  7. Getting closer. https://drive.google.com/file/d/0BwrExtVD005OS2NpTzhwUmpYNlE/view?usp=sharing
  8. Hughes reacts some 8 frames (.43sec) after the anomaly by stopping his camera. Myers has it as a six frame stop. ??? The jump is obvious, in the video.
  9. Tom, If you have a "yahoo" email account, you can go to this link and enter your "yahoo" email address and password and it should give you the capabilities you need. https://www.flickr.com If you do not have an existing account, you'll probably have to create one. Google Drive is fine too, but it doesn't allow you to embed, so you'll have to post the link for your graphics.
  10. Seems like an opportune film gap for the Towner film end and the Zfilm beginning. Besides the problem with Willis' photo not syncing with the zfilm.
  11. Someone didn't do a very good "doctoring" job. Of course, if there wasn't something more original to compare with it, how would we've ever known.
  12. The endpoints consisting of z161(station# 3+29.2-West path) the TSBD corner and 90degrees.
  13. 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.
  14. 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.
  15. 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
  16. 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
  17. 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.
  18. Relationship of rifle location to TSBD corner.
  19. 6sec x 5.49ft = 32.94ft + 52.5ft = 85.44ft 3+29.2 - 85.44 = 243.76 6.25ft (the approx distance between the TSBD snipers nest (2+50) and the TSBD building corner (2+43.75)
  20. Adding more golden elements. See previous chart.
