How can 2% be greater than 5%?? We're talking strict ratios here right?

If you decrease Cd by half, and double A, the drag stays the same.


Compare a car has a Cd of 0.33 and a flat disc with a Cd of 1.0... The car can have 300% the frontal area of the disc but the same drag because its shape has 33% the drag. 300% * 33% = 1
