I knew you did that in your head , good job, I'm ok if it is even numbers, if not I go to my spreadsheet I made that now does that for me.
I also made a spreadsheet in Microsoft excel that calculates line value change on a variable scope, I got the formula from Nightforce some years ago , sincemost of the variable scopes range at 22 or 25 power and go to 42 or 50 power the formula is .
Calibrating range power( /) divided by operating power, Times ( x) line or Gap value=value at various power settings
if you have a scope that calibrates at 22 and you want to shoot at 45 at 600 yards and you have a mil dot,it would look like this
22/45=.489x3.6mil=1.760 at 100 yards x6yards, meaning 600yards =10.56 so, your gap value at 100 yards is no longer 3.6 at 45 power it is 1.760
