Ya I guess it depends on your perspective which is backwards and what you're used to using. I think what's happening is with my other 2 scopes the rifle's zero is adjusted with a screw in the top center of the turret and not adjusted by turning the turret. Once you zero the scope using the screw, you use another 1-3 Allen screws to set the zero stop. However, in the Arken the rifle is zeroed by turning the turret and then afterwards the 3 Allen screws are loosened to set zero stop. Basically doing the same thing but differently. Consequently, the Arken turret needs these extra numbers under the turret to adjust the rifle's zero adjustment downward. The Vortex and Revic does this internally using a screw so you don't really see it externally so their turret rotation numbers can start bottomed out on the tube and count upwards only. The Arken can't start bottomed out. Remember we are talking about the turret rotation numbers stenciled under the turret, not the MIL/MOA numbers labeled around the turret which are later adjusted for zero stop. That's probably as clear as mud.
