Got the D800 back from repair, first time I took it back because focus was nowhere near to acceptable, second time much better but still not spot on but before I take it back again I'd like to hear your opinion.

Today not in the mood to get the tripod, set the ruler bla bla bla so I used a homemade system, a pillow to lay on and the ruler at an arbitrary angle laying on the laptop's screen, took a series of shots from +20 to -20 at steps of 10 from positive to negative through zero, please tell me your thoughts.

Grazie

Your target should be parralel to the camera. The ruler at 45 degrees. That is the only way you can reliably check your camera. Just the ruler at whatever degree you set it is not going to cut it. In the picture below target is parralel, ruler is at 45.
