1) D800 using target A does not focus correctly
2) Send D800 to Nikon service center
3) After repair, D800 using target A now works
Multiple choice:
a) D800 AF was faulty
b) target A was the problem

The point I make (which you seem to object to even though it is accurate) is all of the 51 D800 cameras with images I have looked at at dpreview are ones where (based on Nikon's examples or the vertical AF outer detail requirement) used targets where Nikon say the camera may believe focus has been achieved when the image is out of focus.
Having used Nikon AF for 13 years I do sometimes get wrong focus - but only with subjects where Nikon say AF may not be reliable. This implies the "super secret information" which is hard to miss if you look for it explains why some targets can result in wrong focus
And I and many others will continue to resond with "hogwash". These targets work. I won't attest to ALL of them, but the vast majority of targets are fine. The targets show left side problems reproducibly where no issues are seen on the left. Cameras come back from Nikon with the AF issue is resolved, testing against these same targets.

Many problems turn out to be a lack of intimate knowledge of complex modern camera equipment.
