1/4" for on click at 100 yards will result in 2 clicks at 50 yrds for 1/4" . One click for 1" at 100 yrds is not common now days unless the scope that you have is designed for long, long range shooting. I find that hard to believe considering it is only a 2 power scope. Anything less that one hundred yards you divide 100 by that number and that is the number of clicks you must make to achieve 1" movement of point of impact.

Good shooting
