Rchard, from this . The 2 newer versions have a tendency to back-focus when shooting at their long-end at distances below 10m on modern Nikons. One reason is because they have a feature for calculating distance that’s absent on this version. I’ll illustrate it in my AF Zoom-Nikkor 80-200mm f/2.8D ED repair article. This one does not do it and it focuses perfectly at closer distances. That issue can be corrected properly which I’ll show in the mentioned article.   
I understand that it is possible to fix the tendency to backfocus of the 2 ring version?

Yes. It’s an adjustment to the front group :o :o :o

It’s easier to do on the 2 ring

Sorry to bother you so much. I can´t find your "arcticwolfs" repair manual reference. All I can find is people complaining about the backfocus at close distances issue.
