Interesting, but I wouldn't get too excited by Cd figures to three decimal places. A top aerodynamicist suggested to me that taking three decimal place Cd figures as gospel was basically a fool's errand. (As in, test in different wind tunnels and you'd likely get a larger variation than this.)

Perhaps he's never been interested in low drag.
Perhaps when he's investing $billions on Wall Street he can't be bothered by decimal places.
