I did that on paper figuring out what I said. It wasn't obvious re-reading what I posted.
104^2 * Cd original = 98^2 * Cd changed
Cd changed / Cd original = .8879 = -12.21%
(referencing windows up vs down in 2nd video)
I did watch the both videos (at 2x)
In case anyone was thinking like me at the beginning of this exercise, you can't use delta V because of the square function.
