Hi Western.
You multiply your click value by yardage. But just do 2 for your 200.
So 1/4 x 1(00) = 1/4 inch
1/4 x 2(00) = 1/2 inch
1/4 x 4(00) = 1 inch
Etc.
However, if you have a scope that has hash marks or similar, and you can measure in MOA on your reticle, that is the best way to do it, and forgot "inches". In your example, if you looked through your scope at your 200 yard target and could see that your group was 2.5 moa (which it is), then you just dial your turret 2.5 moa (10 clicks).
I realize your scope reticles may not be capable of this (thinking duplex style), but hopefully as you progress and your scopes progress as well, this will help how you think about measurements.
If that didn't make sense, let me know. I feel like it came out kind of clunky...
Basically, it's easier to measure and dial in corresponding units, vs trying to convert inches to moa or mills, etc. Just get your measurement (if possible) in MOA, and dial accordingly since your scope is already marked in MOA
