Yea, that would make things easier if you did not have to worry about your power setting when ranging or holding over.
For my eyes, a prarie dog at 800 yards requires more than 10x. My Tasco Custom is calibrated at 10x, so I found another calibration point near 20x where I can use half readings. So now, I have 2 sets of range and drop charts to tape to my stock. One for 10x and another for 20x. Confusing, yes, but it works.
