I wasn't actually asking for help, I was trying to offer some information about my personal experience with the 7Dii's focusing issues, in case anyone else was having the same problem and once I find out what is going on, that information might be helpful to them.
What about focus in Live View? Is that ok?
I just finished doing the AFMA for my lenses. All of them ended up in the +2 to -1 range so that validates Michael's comment about not needing AFMA straight out of the box. However, both the 100-400L and the 70-200L II had soft images when coupled with the 1.4x converter so I need to investigate that in the coming week. I have already posted the image of my cat Leo in the 7D II images thread if you want to take a look. That came out ok.
The one thing I noticed is that the 7D II needs light. When there is less light you may get a soft image. You may want to look at this.
