And that was conveyed by JFK's head height above the pavement 52.78" - 39.24"(3.27ft) = (BS head height entry in CE884) = 13.54" span.

Of course they needed the correct height adjustment to coincide with that distance split: 10" + 3.54" = 13.54" / 12 = 1.1283...ft x 18.3 = 20.6485ft

Time to break down this equation some more: http://educationforum.ipbhost.com/topic/22692-swan-song-math-rules/?do=findComment&comment=328073 30.86ft = 20.66(19.76 +.9) + 10.2 496.16 - 20.66 = 475.5 465.3(extant z313) + 10.2 = 475.5 475.5 = My shooter's LOS through JFK @10.2ft farther west than extant z313 while traversing Altgen's.

HSCA Excerpt: "The bullet passed forward through his head and exited at the right coronal suture at a point 11 centimeters forward of the entry wound and 5.5 centimeters to the right of the midplane. This exit point was 1 centimeter lower than the entrance wound, using as the exterior vertical reference a line drawn through the President's brow and upper lip. Thus the bullet was traveling 18.6° to the right relative to his midplane and 5.0° downward relative to his facial axis." 11 centimeters = 4.33 inches

Give me a break. Here's a collage for orientation purposes. World class conspirators would have you believe the shots came from the TSBD and the North Knoll. Would you like to list who ran to the South Knoll and the Carport looking for shooters? What spectator heads were fired over? Go back and re-read so you can pass along the correct information about the path of the bullets.

How could JFK slam into the back of the seat before the 2nd headshot was even fired? .71 seconds after the extant z313 shot. Do the math. Did the big brain explosion at Z313 come from the first of two shots or the second of two? I suggest reading the SS agents descriptions in the followup car. The concept which you fail to understand is "two shots melded into one". Neither of which came from the sniper's nest.

The difference between (a headshot from the overpass and from the steps on the South knoll) is the difference between the (convertible top support frame and the window half open on Jackie's side). Eventually, Nellie moves her head down down slightly toward Greer, at approx z305 she's finished, the window(no pun intended) of opportunity arises from the Southknoll steps, allowing the shooter an opening over the half open window, with JFK looking at crosshairs.

This, coming from a person who can't explain the visible lack of brain debris exiting the rear of JFK's head on the extant Zfilm. Nor, the incredible speed at which Jackie moves back into her seat with her elbow planted on the trunk lid. Maybe old Mr Zapruder pressed downward 1/4" and filmed a few more frames than he thought. For those that are counting impaired, there is a frame counter in the lower left part of the 48fps film. No, Chris D. realized his LOS mistake and duly corrected it by informing people of the new LOS. More reading necessary, then you can understand what I'm saying. But, I'm not counting on it. https://drive.google.com/file/d/1tIR2rrNCmu2Mb8nLJB-ZGkXGGii5ktrO/view?usp=sharing https://drive.google.com/file/d/1CFdpSs8Bt4f-GVJOCOl2wDXdpu-uNjQX/view?usp=sharing

Extending the intersecting LOS via extant z313. Views from both ends.

The aerial is a frame from one of the JFK specials about shot locations. In this special, the conclusion was not representative of the (thin white line LOS). In fact, that thin white line and the LOS it creates (Imo), was never mentioned. Yet, if you use the LOS to my shooter from Bronson(plotted at right) and intersect that with the white line LOS which also intersects extant z313, you can see they both intersect at the same approx location=white wall. Whoever created that aerial knew the shooter didn't lead back to the 6th floor, look where the (white line) endpoint lies to the north and (south for that matter). https://drive.google.com/file/d/1Tfri3lQIklXIPBWju3b8M-_NUKdDayUI/view?usp=sharing

Bonar Menninger on Donahue's study: "First, the fatal bullet’s trajectory was not compatible with a shot from Oswald. The entrance wound in the back of Kennedy’s skull was just to the right of the the crown, or hair whorl, and the exit point was centered in the upper-right portion of the skull. This indicated a bullet path of left-to-right and down at a relatively shallow angle, not right-to-left and sharply down, as would have been the case had Oswald fired the shot. A bullet from the sixth-floor window of the book depository should have exited the center or left side of the president’s face, not the upper right, frontal portion of his skull, based on the position of Kennedy’s head at the moment of impact. The actual trajectory led directly back to Agent Hickey’s position in the left-rear seat of the follow-up car."

HSCA excerpt: "This exit point was 1 centimeter lower than the entrance wound, using as the exterior vertical reference a line drawn through the President's brow and upper lip." Incorporate the 4.23ft distance along with the 3.54" move from EOP to Cowlick location. This means you are decreasing the angle from the shooter. From graphic above: 2.41deg. - .44degree = 1.97deg = Last sentence above basing his conclusion on a Cowlick entry.

Too speculative for me. Bothun is approx 25 seconds after the extant z313 head shot.

Connection for distance difference, not shooter location.

Excerpts from HSCA: Gerald Ford's baby. "To determine this trajectory, the Panel first had to locate the entrance and exit head wounds as precisely as possible. Figures II-6 and II-7 show where the fatal bullet entered the back of President Kennedy's head at a point 9.0 centimeters above the external occipital protuberance. *The above conclusions differ to some extent from the testimony given by Thomas N. Canning before the House Select Committee on Assassinations on Sept. 12, 1978, in each case, the differences reflect new information or analysis resulting from work concluded subsequent to the presentation of preliminary findings at the hearing. *The interpretation of the head wounds used in defining trajectory reported in testimony on Sept. 12, 1978 differs from this report because the final illustration from the Forensic Pathology Panel showed the exit wound to be 1 centimeter lower than the entrance, rather than level with it as had been concluded earlier. Thus, the resulting trajectory is somewhat steeper." 9 centimeters = 3.54 inches Mr. SPECTER. When you say 52.78 inches, which individual would that be? Mr. KELLEY. That would be the President. Mr. SPECTER. And what part of his body? Mr. KELLEY. The top of the head would be 52.78 inches from the ground. 52.78" - 10" - 3.54" = 39.24" = 3.27ft = (CE884 JFK height used to fit trajectory back to TSBD 6th floor.)

Intelligent people realize Prophylaxis and Prosthesis are not syn·on·y·mous. Therefore, there are two questions asked. We realize this to avoid: re·dun·dan·cy The state of being not or no longer needed or useful. The use of words or data that could be omitted without loss of meaning or function; repetition or superfluity of information. If something is implied, it is understood to be true or to exist, although it is not stated directly or in a legal agreement

If-then statement: The if-then statement is the most basic of all the control flow statements. It tells your program to execute a certain section of code only if a particular test evaluates to true. If this test evaluates to false, control jumps to the end of the if-then statement. The dental form asks two separate questions. 1.Is a Prophylaxis required? Answer: Yes 2.Is a Prosthesis required? If Yes (implied), enter data. Answer: Failed 5-5-58 If No, data entry unnecessary.

A few more excerpts: The fatal bullet’s performance was, however, completely consistent with the .223 round fired from the AR15, the predecessor of the M16 rifle issued to American infantrymen during the Vietnam War. Although the .223 incorporated a full metal jacket to comply with Hague Convention mandates, the design was essentially a work-around to ensure maximum lethality in combat. An extremely thin copper jacket, coupled with the bullet’s light weight and the AR15’s high velocity, causes the round to tumble and rupture upon impact. The lead, which has softened beneath the jacket due to the bullet’s friction with the gun barrel and the air, cascades out in a random pattern of spherical fragments, which quickly solidify as they strike much cooler bodily fluids and tissue. The copper jacket also breaks up, and the combined result is a devastating, shredding and frequently lethal wound characterized by multiple, minute shards and irregular fragments — exactly like the injury Kennedy suffered.

"Tissue can contract, and bone can shrink due to low-velocity trauma. But the high-velocity impact of a rifle bullet — particularly in the strong, thick bone at the back of the skull — produces a different and very brittle response. Holes in the skull made from high-velocity rounds are reamed out as the spinning bullet bores through, pulverizing the bone, and thus invariably are slightly larger than the diameter of the bullets that cause them. The .223 round used in the AR15 is 5.56 millimeters in diameter, or just a touch smaller than the 6-millimeter entrance wound. The wound’s size, therefore, was consistent with a shot from Hickey." Right bullet (or similar), wrong weapon, wrong location. The XP-100: https://en.wikipedia.org/wiki/Remington_XP-100 Cartridge .22-250 https://en.wikipedia.org/wiki/.22-250_Remington Cartridge 6mm-BR. https://en.wikipedia.org/wiki/6mm_BR

Very close to the same trajectory, they just had the wrong location. Elevation = 430.2 - 418.25 = 11.95ft 2.41 degrees gets you 186.5ft away. That would be a head height of 52.78" - 3.54" = 49.24" = 4.1ft above pavement. Lateral angle (left to right) from my shooter to 4.2ft past extant z313 = 1.2 degrees My shooter's bullet would have been 3.9 degrees to the right of the follow-up cars centerline at extant z313.

Still the same LOS from Bronson, just extend the shooter back to near the carport. (Sorry, didn't pick up that perspective from Bronson initially.) The LOS to JFK is now the North side of the Stemmons sign. The bullet that hits JFK approx 4.2ft farther down than extant Z313, travels between Doris Mumford and Gayle Newman who are 7ft apart from each other. The shot is approx 186.25ft away. Slight change in perspective as it's farther down the Annex Rd.

The XP-100 was initially introduced with a 10¾" barrel set into a nylon stock with an unusual center-mounted grip. Chambered in .222 Remington in early prototypes, the short barrel produced significant noise and muzzle flash. Subsequently the case was shortened to reduce powder capacity to a volume more suited to the shorter barrel of a pistol. The resulting cartridge, the .221 Fireball, produced factory loaded velocities of over 825 m/s (2,700 ft/s) from the short barrel, and accuracy rivaling the parent .222 Remington, one of the most accurate cartridges made. 1frame/18.3 = .0546... sec x 2738ft per sec = 149.617ft = see graphic above

Personally, I think it looks more like this type of muzzle. https://drive.google.com/file/d/1TFvyjnpHuIcbLuhapYXcjEx0Nn5WqStf/view?usp=sharing,

I don't believe that's a dog muzzle.
