Picture shows Willis in Martin's film. He's off the steps and according to Myer's is 12.68 sec. from frame 313. Willis has a total of 16 sec. to run from his last photo#3, to get to where we see him in Zapruder 133. So from his position in Martin, he has approx 3.2 sec to get to where we see him in Z133. If 200 ft. approx, is the distance from the Houston corner to where we see him in Martin, he ran to it in 13 sec. approx. This equates to 15.3 ft. per sec, or 10.43 mph. chris
