The distance traveled by the common object from z193-z257 = 73ft.

Z camera at 18.3 frames per sec.

At 1.47ft per sec (1mph) the math awaits.

64 frames/18.3 fps = 3.497 sec

73ft/3.497sec = 20.874ft per sec = 14.2 mph

Myer's frame rate for Towner's camera = 22.8fps for his multi-sync hypothesis to work.

Excerpt from Gary Mack on Towner's film: "The Towner film's true speed is likely closer to 18fps or slightly faster for most of the reel than to any other speed; it certainly was not operating at 16fps on November 22, 1963. Gary Mack"

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

73ft/3.497sec = 20.874ft per sec = 14.2 mph

The correct equation will now read:

73ft traveled at 3.497 + 1.8 sec = 5.297 seconds = 

13.781 ft per sec /1.47(1mph) = 9.375mph

That would be a match.

And, since Myer's has the motorcade slowing, moving into the Elm St turn, there is no chance in h_ll that it ever approached 14.2 mph.
