I'm curious as to the distance from the SN to the limo at frame 200. You have 130'. IIRC, the limo/SN distance has generally been held to be 195' at frame 220. The limo is rolling at about 12 mph at this point, that is a tad under 18ft/s. Frame 200 is 1.2 seconds before that, so the difference in distance should be around about 20', not 65'. Anyway, that's the back of the envelope version.
Thank you Mitch, just got a years worth of math classes for free. Let me see if I can plug in the numbers for 500ft/sec later. I calculated 130' from the "distance from C" shown on the Zapruder exhibits from the WC showing 186 and 207.

I used 62 ft for the window sill, it looks like the WC used something else. The WC looks like it erred when they calculated the angles as well. 24 and 22 degrees are significantly different than your 27 degrees. Thanks again.
