I can't say they weren't as sharp as possible, since they were all the same - I would say they were reasonably sharp at least, not like the lens when it was new and unadjusted.
First thing to say is that the AF/FA adjustment is not about "sharpness", but is about front or back focus. If a lens cannot give "sharp" images then AF/FA wont help that.

I'm using the "one only" adjustment mode,
If you are using the Adjust One menu to adjust the lens, make sure your AF/FA menu is in Adjust One when you exit the menu. Otherwise it may not be applied.
The protocol is:
AF/FA Menu OFF................. No adjustment will be made
AF/FA Menu Apply ALL..........Apply all setting will be used for ALL lenses (including ones that have been individually set in "Apply One" menu)
AF/FA Menu Apply One.........Apply One setting will be used for lenses that have been individually calibrated. Mounting a lens with no calibration and the camera will uses the Apply All setting

All the tests were center-point only, not that that should matter on a flat test target.
The target must be at an angle, otherwise how can you see if there is front or back focus ?
