Try zeroing it at 20 yards. That way, you'll just have to point and shoot for anything out to 35 yards (unless they are closer than 10 yards in which case the poi would be around one mil dot lower than the center of the crosshairs).
The further out your zero is, the more variation there is from shot to shot. I.e. If all the pellets went inside 1/2" and 50 yards, that would be great but it would be harder to know which hole was the "real zero" if you sighted in at 50 yards.
At 20 yards, my Cricket 25 will put every pellet in the same hole and, even with a cheaper scope, I can still see all the pellet holes clearly, so sighting it in is very easy at that distance.
My Cricket is sighted in at 20 yards and I can tell you from experience that there is very little to think about in terms of corrections for shots out to 35 yards and a very still mil dot correction for 50 yard shots.
Once you sight in at 20 yards, check it by taking shots at 40, 50 and 60 yards so you can check it's on the center line still and so you can map the drop at those distances.
