I have heard that the Gen III can be a be even more finicky than the Gen II-E when it comes to adjusting for 1x. At one point, Steve Fisher told me that he found the Gen III to be even better than the Gen II-E on 1x. I'm kinda curious as to just how much of this variance is due simply to settings, non-uniformity in manufacturing, how much is actually something with each person eye, etc.
