Another question, slightly OT for the thread:

Which has more effect, reducing frontal area, or reducing Cd by the same percentage?

Say we take a bullet, with a Cd of .24, and a frontal area of 50 ft^2.

In one test, we reduce the bullet to 45 ft^2, a total of 10% reduction in A, but Cd stays steady at .24

Now in the second test subject, we reduce the Cd by 10%, to .216, but leave the A the same.

Which reduction would have the most effect? My initial thought is reducing A having more effect comparatively, all other things equal.
