Mil/Moa Adjust multiplies the distance moved per click. This is because you scope
may not measure angles correctly.
A 10" target at 95.5 yards is 40 1/4 moa clicks across. But your scope may give you
10.5" of movement at that range.
If you type in 10.5 here that multiplies the amount of movement per click by times
So 10" is now 9.5* moa at 95.5 yards, to match your scope.
*(to be picky, 9.5238, 10*10/10.5)
"In my experience, more than 50% of the time error in trajectory prediction at long
range is actually scope adjustment error." - Bryan Litz
