If the original data is three decimal places, then there is no issue deriving data to a higher level of precision (than you could with two decimal places), but even then it is still +/- 0.0005 and so no further precision can be gained.
Indeed you did, I didn't re-read the thread. It is very important and one many people on here don't fully understand, see below for one example, perhaps unfairly cherry picked, but certainly, and unfortunately, representative of many people here on ecomodder.

I simply stated that, in order to satisfy 6.3% higher drag than the value which was provided, required 6-decimal place accuracy.
