First your test shots, maybe try with a sloped ruler and a proper target and you will see what the actual difference it makes. Why do you think the focus char tools and focus pyramids are not 6-8 feet deep? Maybe have a read of this - https://www.the-digital-picture.com/Photography-Tips/af-microadjustment-tips.aspx

I beg your pardon! Are you denying the reality that my sample photo focus changes between zero and -20 is about 6 feet?

I don't think anybody would be surprised that that could be the case. But actually, I don't think you can tell what the camera focused on, since both the branch and the wall are within the focusing spot. That could be the cause of your problem.  Like the man says, you need a proper target.

And I'm sorry you had trouble adapting a commercial target to a long tele. Not my problem.
