Andrej, I think I have to correct that back to 2.379ft past the extant z313 location. The 4.5ft mark was only part of the adjustment process which I will soon explain. Irregardless, Tom was right about the syncing problems that he mentions in the interview.

Moving along, please remember I am using the info/data supplied by an entity that was intent on connecting all the dots/shots back to the TSBD 6th floor SE window. The false information supplied allows this to happen. For example, when the testimony states that JFK's head height above the street was 52.78", this was used in accordance with the rest to end up back on the 6th floor. Don't assume for a second that this is an accurate measurement. That said, I believe by "picking out info between the lines" and explaining it in the context of the WC fantasy, hopefully you're gaining a better understanding of how they went about it.

The rifle barrel end elevation (upper right red box) was set at 492ft for extant 313. The z313 street elevation (lower red box) was 418.48. 492 - 418.48 = 73.52ft Remember, you still have to subtract JFK's height above the street = 52.78" - 3.54" = 4.103ft 73.52 - 4.103 = 69.417ft As can be seen, a difference of 10" versus what the original survey shows @ 70.25ft You think they were "boxed" in to that location.

Since the early investigations were also trying to manipulate 10", I'll give you a tie-in to the previous post. A ten inch elevation difference on a sloped road of 3.13° = 15.25 horizontal feet. The distance between JFK's position in the limo and the front end equaled 15.11ft or a difference in distance of 1.68 inches = close enough match for their task at hand. The chalk mark designating a throat shot would be at the limo's front end(elevation 10" lower) location when a headshot (10" higher than a throat shot/chalk mark) occurred at JFK's physical location in the limo. Simply put, the above describes the elevation difference between 3.27 and 4.103ft = 10"

Why would an investigative body use the same bullet hole location (think chalk mark elevation) when determining the ballistics for a shot that hit JFK in his head? Once you realize how preposterous that is, the following might be much easier to understand. The difference in JFK's head height at z312 was 3.54" lower than when he was sitting upright. Where did the other 10" go? Please don't fall victim to the vehicle height difference BS. btw, the extant zframe is rotated 3.13° clockwise (slope of Elm St at this location) to fit the recreation.

Tom was close at 4ft farther down Elm. Documentation proves out to 4.5ft https://drive.google.com/file/d/1T_L-ofjszZmZnMK9raiElwQfYA9YjZqx/view?usp=sharing

How does the overall sync at extant Z447 work out? Firstly, you should have a better idea now why the frame numbering for the extant zfilm wasn't introduced until late Jan 29,1964 by Shaneyfelt. Converting the acoustical info from Thomas pertaining to the time between extant z313 and the next shot = .46sec = 8.43 zframes@18.3fps, I'll add this amount(excised frames) to the total original frame count using Wiegman's 24fps rate: 24 x 11sec = 264 frames / 1.311(conversion from 24-18.3fps) = 201.37z frames + z252 = z453.37 201.37 - 195(447-252) = 6.37 zframes The difference between these two being 8.43 - 6.37 = 2.06 frames Where does the two zframe difference come from? I'll use Z's reaction sync to the last registered acoustical shot at z331(see above) for the calculation. z331- 252 = 79 zframes / 18.3 = 4.316sec 453.37 - 331 = 122.37zframes 122.37 - 2.06 = 120.31zframes 120.31zframes / 6.684sec = 18fps When the film slows from 18.3 to 18fps after extant z331, the two frame difference is accounted for.

btw, The reaction to the last acoustical entry in Wiegman would have occurred as he was panning(many blurry frames) back towards the front of the TSBD, so it's rather difficult to decipher when/if the reaction took place. There are more acoustical entries. The previous two before the z310 shot would work out to this: z310 - 4.83sec x 18.3 - 88.39(Thomas 140.32-145.15) = z221.61 Z221.61 - 1.05sec x 18.3 =19.21 (Thomas 139.27-140.32)= z202.4 And no, I really don't want to get into another discussion about shots prior to the limo stop area. Start or add to an existing topic for that. Is the acoustical evidence valid, you can decide for yourself. I thought I would add it to the Wiegman sync/missing frames/limo stop/multiple shots scenario and see how it fits.

The last acoustical shot entry is .69sec x 18.3fps = 12.62 frames after the z318.43 shot. If there was no interruption in frame sequencing between z318.43 and 12.62 zframes the last Thomas entry would equal z331.05. But, by z318.43, the removal of 8-9 frames is in progress. 318 318A. 319 319A. 320 320A. 321 321A. 322 322A. 323 323A. 324 324A. 325. 326. 327. 328. 329. 330. 331. Starting after 318A, count 12.62 frames which runs to 325+. Z325+ to Z331 = approx 6z frames x .0546sec per frame = .327 seconds If .3sec is a reasonable reaction time for a shot then the outcome viewed in z331/332 appears to sync.

The second shot response in Wiegman appears at Wiegman 93/94(remember to add one to each as my frame counter starts at 0). If I use the middle frame labeled as 92 but is actually 93 ( I see a little shake beginning and continuing on through 93) the second shot acoustical equation becomes: Wiegman93Reaction = .249sec /.0546 = 4.57 zframes x 1.311 = 6 Wieg frames = Wieg 87.12 = shot2 / 1.311 = 66.45 zframes /18.3 = 3.63sec 66.45 z frames - 58.02 zframes(z252-z310) = 8.43z frames /18.3fps = .46sec between shots = Don Thomas acoustical.

Look above. The Wiegman film starts at z252 + 58 frames later = z310 = shot, not reaction to the shot CE884 last data entries are z255-z313 = 58 frames Once again, do you believe the WC took into account Altgens and the acoustical evidence when syncing/manipulating their masterpiece?

See if I can simplify this somewhat: Look at the data chart: frames 161-313 = 152 frames Move the start to 166 - 318+ = the same 152 frame span Start with a shot at 310 add the acoustical result of 8.4 z frames = .46seconds 310 + 8.4 = 318.4

Rick, If you've been following the thread, you might realize I've purposely stayed away from any witness testimony except Hickey I believe. Using his testimony, I applied his hair-flap description to the zfilm around z274. In retrospect, I think he was probably describing the z310 shot quite possibly converted(blob wise) into the extant z313 frame. I don't feel the need to argue whether or not there were two hits to the head, and I have no reason to doubt all the Parkland staff. What is obvious to me is there were two shots within a time frame which would not include one shooter. That aspect, along with a limo instantaneous stop and the math used to accommodate the frame removal sequence is what this is about. Was the frame/s with the obvious second shot(frontal location) removed or is extant z318+ a combination of an instant hit and camera reaction. The acoustics are a wonderful addition. CE884 is the data chart. The limo was not traveling 2.24/3.74mph using either chart at the designated time specified. It was traveling that speed at another point during the assassination. It's quite obvious now, (see previous posts) when that occurred. I just continue to show how the WC went about their business.

Let me introduce some acoustical data into the equation now. Thomas’ time between two shots = .46seconds x 18.3 fps = 8.41zframes Z310 -318.4 = 8.4zframes I’m the WC, I need to make the 2nd shot disappear, but have to base my alteration/adjustments on what the true frame count / limo traveled distance was. 5 frames @.9ft (CE884 - z161-z166) / 8.4 frames = ratio of .6 / 1 .6ft per frame ratio = Limo speed from Z301-Z313 .6ft per frame x 9 frames = 5.4ft 5.4ft = 3 frames @ .9ft (CE884 - z168-Z171) using 18 whole frames or 5.49ft using 18.3frames = 1 second. The retarding of distances between the two headshots appears in the two CE884 data charts. This is why (among other items) you can rest assured that the frame removal process resided within a 1 second real time span. So, did the WC also possess the acoustical evidence besides the original Zfilm to help them figure out what alterations were necessary? You decide for yourself.

Eddy, We are now pretty much in agreement. I thought I made it clear that once the radius for the motorcade is corrected the 38 missing frames is no longer valid. A tighter turn puts the Mayor's car out of Altgen's LOS because of Brehm and the african-american gentleman extending the blocked view of the cars rounding the corner. Altgen's photo aligns with Z255. Wiegman starts at Z252. Mark's supplied Wiegman frame is five Wiegman frames from the start. 5 / 1.311 = 3.81z frames = Z255.81 A photograph is one moment in time. Altgen's just missed the Mayor's car front end because of Brehm and the african-american gentleman. Remove them and I'm quite sure we see the front end of the car. If you want a better idea of the turning radius started by the limo, look at Towner's film as it traverses the first lane marker and compare it to where Mark has the limo in the same position. The turning radius is incorrect, too wide. Yes, Meyers used 24fps and counted back 11 seconds placing his Wiegman start at Z246, but this was all based on his placement of Wiegman's camera movement for a shot at Wiegman frame 89. Actually it's Wiegman 90, but it's not the first shot that he has Z313 synced with, it's the second shot. Think Acoustical syncing. Once you realize this, you might have a better understanding why there are 8-9 frames missing from the extant Z film between approx Z316-z324. One other bit of information, all the films may appear to sync around the extant 313 headshot and shortly thereafter, sorry this is incorrect.

Correction: The reaction sync between Wiegman/Z is Z313. Remember, my Quicktime counter starts at 0 so the actual Wiegman frame would be 80, not 79. A 24fps -18.3fps ratio = 1.311 x 3 frames = 3.93 Wiegman frames 80 - 3.93 = Wiegman 76.07 Wiegman 76.07 / 24 = 3.1695seconds 3.1695sec x 18.3 = 58 z frames Z310 - 58 = Z252 The Wiegman film started at Z252

Once the ballistics are worked out, just look for a dark figure on the ledge. Then compare it to another representation. The limo is on Houston St. as the gif plays.

btw, The shot from behind could have missed and the blob was added to give the impression of a rear shot at that moment. I just believe that the forward movement of his head circa 313 is an indication of a shot. And, as you said, impossible for 1 shooter. But, this is more about timing using Wiegman's film as the clock, comparing it to the acoustical and showing the after affects of a limo stop/frame removal process. More coming.

Using the 338ft distance above for bullet travel: 338ft/2060ft per sec = .164/.0546(1zframe) = 3zframes bullet travel time. This is what I used for the z310shot - z313 hit. I'm not inferring that I believe the shot came from the M.Carcano. This is more for the timing aspect. Mr. FRAZIER - The first shot, Lot 6,000, the velocity was 2199.7 feet per second. Shot No. 2, Lot 6,000, velocity 2,180.3 feet per second. The third shot, velocity--same lot--velocity 2,178.9 feet per second. The third shot, velocity--and this is Lot No. 6,003--velocity was 2,184.8 feet per second. The fourth shot, Lot No. 6,003, was 2,137.6 feet per second. Fifth shot, Lot No. 6,000, 2,162.7 feet per second. The sixth shot, Lot 6,003, 2,134.8 feet per second. An average of all shots of 2,165 feet per second. Mr. EISENBERG - How would you characterize the differences between the muzzle velocities of the various rounds in terms of whether that difference was a large or small difference? Mr. FRAZIER - This is a difference well within the manufacturer's accepted standards of velocity variations. They permit in their standard ammunition manual, which is a guide to the entire industry in the United States, a 40-foot-per-second, plus or minus, variation shot to shot in the same ammunition. . The muzzle velocity would be near 2244ft per sec, reduced to 2060ft per sec at 113yds=339ft 2199.7 + 40 = 2239.7 fairly close to 2244. Ballistics chart:

What other location at least 15ft above the TSBD 6th floor would fit the location, especially using the WC matching bullet 15.35° trajectory. The obvious answer would be the TSBD 7th floor or rooftop, but then the trajectory changes to a minimum of 18.15° from the 7th floor ledge and steeper from the roof.

The Dal-Tex 6th floor is 10.5ft higher than the TSBD 6th floor. 161.1ft vs 171.6ft The elevation difference between z313 (88.8) labeled on Drommer and the DalTex building (101.0 ) = 12.2ft Each DalTex floor(minus the bottom floor) is at least 10ft high. Possibly higher because of the 6th floor elevation differences. Start at the TSBD 6th floor window ledge elevation of 61.1ft(I used Robert West 61.2 in the graphic) 61.2ft + 10.5ft (DalTex 6th floor ledge) + 10ft (DalTex 7th floor ledge) + 12.2ft (DalTex base to z313) minus JFK’s head height above pavement 52.78” = 4.4ft Total = 89.5ft displayed in graphic. This means the DalTex 7th floor is at least 20.5ft higher than the TSBD 6th floor. Keep this in mind moving forward.

Ian, That's a valid point. At 7.47mph I don't know how a human head would respond(already shot from behind) to the initial braking. For now, I'll stick with the initial limo distance traveled at approx 2.4ft(braking calculator) = 4 zframes @ .6ft per frame stopping at z318 1/2. If the head is supposed to move forward, I think you'll have an even more precise time for frame removal.

The WC didn't lie about the angle(15deg21min = 15.35°) from which the z313 headshot hit JFK's head. They lied about where it originated from. I'll explain the rest of the graphic in awhile. Sheldon Hershorn had it pegged.

Paul, my interjection above in red. It's also impossible to initially see JFK's head start the "back and to the left" process at z315 in real time. More coming.

Z310 Shot From Behind - Z313Hit- Z314+ Shaneyfelt Brakes - Z318 Limo Instantaneous stop - Z318.41Headshot from the front / Remove 8+ Frames Essentially two shots in one with the braking reaction giving the false impression of the initial "back and to the left". Audibly possible, visually impossible to distinguish between the two shots in real time. imo The Z313 headshot came from the DalTex 7th floor ledge:
