The problem with these formulas is you don't know what numbers to plug into it.
Here is a real example of what little change can make a big change in the numbers.
Back in the day I used to work on airplanes. I guy came into my buddies shop and wanted to change all the button head rivets on his plane to flush mount rivets. It was a big job but my buddy did it. The plane picked up 7 or 8 MPH. I would never have believed such a little change could make such a big difference in drag.
My point is, you can plug in any numbers you want on the front end and the program will spit out any numbers you want on the other end. Cool to play with but of no real use unless you have a wind tunnel at your disposal.
