stop watches are inaccurate up to like +/- 10 mph. blinking, breathing, twitching, and a bunch of other homeostasis activities all come into play. plus, he needs two exact distance markers to get an accurate distance to divide the time it took for you to cross that distance (time clocked on the stopwatch) for the equation to find your average velocity. (cant be speed because you need directions based on the specific topography, which i doubt he found out) so was there an exact distance he measured out? was there anything blocking his line of vision crossing the 2 distances? how far was the distance? what was your time clocked on the stop watch? seems like a lot to do and then to pull you over so quickly, especially since you are familiar with the area and were seconds away from your destination.
yes, i've used this before
