I originally, set the fast focus eye ring looking at the sky for the sharpest, clearest reticle as most manufacturers suggest. The other day I decided to turn the adjustment ring while looking at my 100 yd. target. The strange thing was it was like turning the power setting up and down? I was able to bring the target up much larger than it was when I first looked through it is this the correct way to adjust this setting or, should it be adjusted the way I did the first time and left like that for all ranges? At this point I'm pretty confused lol!
