I know graphs do not help you much Cd, but it is all I can do for the time being

Here is a comparison of coast-down speeds with my current 0.269/0.01 combo versus 0.33/0.012. The numbers are a stock Zx2's Cd and a hypothetical increase in RR due to placecard air pressure.

The pink line is the hypothetical coast-down during a duration of testing a stock ZX2 in the same conditions as the original test. The dots are the data points for my coast-down test where I came up with Cd= 0.269, Crr= 0.01



Note the incredibly high Sum of Error^2. This shows the amount of deviation from my data points and it is quite a lot!
