Just a question: About the back focus, did you try AFMA ? If yes, how effective was it ??

I reckon the back-focusing in my sample is not related to RSAs if you mean that.
But sorry, I've to return the lens today so I can't look into this any further.

Did it back focus only in One-Shot mode (focus priority) or also in AI-Servo mode? Or did you not try that?

The lens does not only measure nicely (sharpness), but also is very nicely engineered:
