You seemed to have missed my point.
My point is that comparing Cd figures of cars to three decimal places is rather moot, when the variation between different wind tunnels is likely to be greater than that.
Your point appears to be that the development of aero on a specific car in a specific wind tunnel involves measurement down to three decimal places.
Two different ideas - one absolute, one relative.
