10 ÷ 1.047 ÷ 1000 x 100 = .955 moa
Your right, that's no big deal if you're doing a second shot correction on a 10 inch miss.
On the other hand if you're shooting at 1000 yards and cllick up 22 MOA thinking you're getting 220 inches from a 100 yard zero your shot will be about 10 inches high. That may be why "you are off by 10" at 1000 yards" with your first shot. And when hunting how do you see the impact at that distance to know how far you were off?
If you can see bullet impacts why do any calculations? Just walk your shots onto the target. ;-)
