I guess I could calculate it if I wasn’t so lazy, but if your shot takes 9 seconds to reach it’s target, among all the other corrections you’re dialing in, do you have to take the rotation of the earth into consideration? Or in other words, is that a tougher shot if you’re shooting North or South, rather than due East or due West? (Not to be confused with a little village in South Carolina).
You very much have to take the Coriolis Effect into consideration, even at 1000 yard shots shooting NS vs. EW can make a noticeable difference. It’s all depending on how close to the poles you are as well.
