Question 1:

Why does the Z film start at frame 133?

Frame 133 is 33 frames more than frame 100.

Or, 33 frames @18.3 fps @11.3mph = 30ft.

Question 2:

If Dale Myers were to use the correct Frames Per Second rate for the Tina Towner film, what would be the total frame difference between the two?

168 Total Frames

Myers 22.8 FPS

Correct Speed 18.3 FPS

4.5 FPS difference

168/18.3=9.18 sec.

9.18 sec x 4.5 FPS = 41.3 total frame difference

chris

P.S

Tom, does 41 or thereabouts, sound familiar?

Chris...you are doing important calculations here, which are not going unnoticed.

Question 3:

How much farther down Elm was the Altgens head shot, in relation to the 313 head shot?

4+65 to 4+95 0r 30 feet.

Thanks Jack,

I believe once I'm through with this topic, many eyes will open up.

Question 4:

If Tom Purvis figured out the frame count total between the 2 head shots, would Dale Myers give us a confirmation on that, using the Towner film up around the Elm St turn?

Tom Purvis: 29.7 feet covered in 2.1857923seconds/40 elapsed frames , = 0 .7425 ' per frame X 18.3 =13.58775 fps X 60 =815.265 fpm X 60 =48,915.9 fph/5280 =9.264375 mph. From Z313 to Z353.

Dale Myers: PG56 of his " Epipolar Geometric Analysis of Amateur Films", limo speed from corner of TSBD to end of Towner film 9.2 mph

chris

P.S Something about the corner of that TSBD building has a warning light flashing!!!

Question 5:

If someone wrote an article for Life magazine way back when, and stated :

A. Throat shot

B. 74 frames later Connally hit

C. 48 frames later head shot

Then the NPIC listed the numbers

190

264

312

in accordance with the article.

Would this have any significance?

All depends on how you decipher it!!!

For instance::

190-33frames=30ft@18.3 fps@11.3 mph=frame 157=frame splice.

190+74=264-33frames=30ft@18.3 fps@11.3 mph=frame 231 or 157 + 74 =frame231

312-33frames=30ft@18.3 fps@11.3 mph=frame279 or 231+48= frame279

chris

P.S. Always remember that 30ft difference. The difference between 4+65 and 4+95.

Question 6:

If frame 133 is the beginning of the limo sequence, and 74 frames (Life magazine article is added) would there be a significance to this?

133+74=frame 207=approx splice frame start.

207+48=frame 255=Altgens photo

255+24(A new common number)=frame 279

There's that 74-48 combo again

chris

P.S. Will introduce the significance of 24 a little later on. Or perhaps, Tom will chime in on this one.

Question 7:

If the NPIC created a document that stated:

1. jfk throat

2.74 frames later Connally

3.48 frames after that jfk head shot

then listed

1. 73.8

2.

3.122.4

How would I decipher that?

Connally hit at:

190+74=264-33frames=30ft@18.3 fps@11.3 mph=frame 231 or 157 + 74 =frame231

Frame 231+122(74+48)=frame 353

Frame 353, that sounds familiar.

It should, it's what Tom Purvis calculated to be the 2nd head shot down in front of Altgen's.

Tom Purvis: 29.7 feet covered in 2.1857923seconds/40 elapsed frames , = 0 .7425 ' per frame X 18.3 =13.58775 fps X 60 =815.265 fpm X 60 =48,915.9 fph/5280 =9.264375 mph. From Z313 to Z353

chris

P.S. Hide in plain sight!! Where have I heard that before.

Chris

I can see You and Tom have put a lot into this and it is appreciated by many.

Would this indicate the cut in the towner film to be non_accidental?. And the timing between the shots remains the same

Just 30 feet further down Elm?.Would this also tell us why the wound ballistics are so confusing as to the angle of entrance ,with JBC and JFK leaning way over to the left and not in an upright position to recieve the wounds makes a bit more sense of the impact orientations.

I wish I paid more attention to math all those years ago.

Ian,

The splice in the Towner film moves JFK in direct alignment with the corner of the TSBD building.

Yes, it was spliced for timing purposes.

As for your other questions, let's see if more can be answered, as I move forward.

Question 8:

What numbers added together give you 74.

33+41

Why might this be important.

9.18 sec x 4.5 FPS = 41.3 total frame difference. From question 2 posting.

33 frames @18.3 fps @11.3mph = 30ft. From question 1 posting.

Question 9:

What numbers added together = 48.

24+24

See question 6

Question 10:

Can a combination of these numbers get us from one point to the next?

Let's try this one to begin with:

157+74(33+41)+74(33+41)+48(24+24)=353

Chris

Frame 100(z) would be at the corner TSBD in line with the towner splice .So if Zapruder did film before the limo this would have to be discarded as it would show the 30 feet difference.anything before that would be ok .IOW this is the reason there is no footage of the turn at Elm anywhere. You do not need to alter it if you are not going to show it.
