RE: your OOPS........
That was a big handicap the PST was given. 24 for it and 20x for the NF should have given the opposite results under any condition.
The thing that swayed my to the NF was completely visceral. Some fellows on the bench next to me had the NXS. I asked to look through it. They said sure. I then asked if I could focus it for 'my' eyes. Again they said sure. Wow what a difference even with a very slight adjustment.
A sparrow size bird was hopping on a bush at about 900 yds. Not only could I clearly steady the reticle on the bird, I could pick any part of the bird. Some where in my future is a head shot on a magpie, oops crow at some great distance.
When I did my scope comparisons it was between Leupold VX-III, Ziess Conquest and NF. The Ziess was 4 times better than the Leuy. The NF was twice better than the Zeiss. I bought the Zeiss, being a conservative fella (read cheap). For my final and probably last build I went with the NXS
Eagerly awaiting your further investigation.
