I think we'll get a better idea of what you summarized in regards to horizontal/vertical points (measuring sticks) with a few examples:
Mr. SPECTER. Was there any difference between the position of President Kennedy's stand-in and the position of President Kennedy on the day of the assassination by virtue of any difference in the automobiles in which each rode?
Mr. SHANEYFELT. Yes; because of the difference in the automobiles there was a variation of 10 inches, a vertical distance of 10 inches that had to be considered. The stand-in for President Kennedy was sitting 10 inches higher and. the stand-in for Governor Connally was sitting 10 inches higher than the President and Governor Connally were sitting and we took this into account in our calculations.
Elm St slope = 3.13degrees = 1ft vertical per 18.3ft horizontal
10"/12" =.833ft
.833ft x 18.3 = 15.2499ft
15.249ft = DISTANCE FROM JFK WITHIN LIMO TO LIMO FRONT BUMPER

The 13.54inch vertical span in terms of horizontal make-up.
10inches is from above with a remainder of 3.54 inches.
3.54 inches/12inches(1ft.) =.295ft
.295ft x 18.3 = 5.4ft(horizontal)
Mr. SHANEYFELT. Yes; because of the difference in the automobiles there was a variation of 10 inches, a vertical distance of 10 inches that had to be considered. The stand-in for President Kennedy was sitting 10 inches higher and. the stand-in for Governor Connally was sitting 10 inches higher than the President and Governor Connally were sitting and we took this into account in our calculations.
Mr. SPECTER. Was any allowance then made in the photographing of the first point or rather last point at which the spot was visible on the back of the coat of President Kennedy's stand-in before passing under the oak tree?
Mr. SHANEYFELT. Yes; there was. After establishing this position, represented by frame 161, where the chalk mark was about to disappear under the tree, we established a point 10 inches below that as the actual point where President Kennedy would have had a chalk mark on his back or where the wound would have been if the car was 10 inches lower. And we rolled the car then sufficiently forward to reestablish the position that the chalk mark would be in at its last clear shot before going under the tree, based on this 10 inches, and this gave us frame 166 of the Zapruder film.
It's back to CE884 we go.
Warning!!! The distance traveled between Z161-166 is listed as .9ft which equates to 2.24mph.
What would happen if we determined what the true distance traveled and speed should be, at least according to the extant zfilm and survey plat?
