Though, i kinda can't really understand how to do this. I made some screenshots and got pictures ~2.65 size in scope while fov is 1/2. If i just devide 1/2.65 i get 37.75..... popular 0% MM value. if i divide 51/103 i get 100% MM 50 RSS. Can't get why they differ and why just having 38 OR 50 can be 1:1.
You can not explaing this but eh, is solution even exist?
