He covered the 200 m speed trap in about 6 seconds but I don't see a positive slope through that, nor through the preceding km.



Well, I don't know the exact air density at Battle Mountain that hour that day (but I have air density from weather stations in Winnemucca and Elko from earlier in the day and later in the evening) so I had to make a guess about that. But given that guess, I got a CdA just a hair under 0.02 m^2.
