While I appreciate your effort and your reply it doesn't have anything to do with the focusing screen per se. One could even add a metal plate and the camera would focus just fine.
I'm after a solution for my focus being off.
Edit:
This picture (

Edit2:
This one I have just taken without any micro adjustment at all. Focused on the "b". What the *#~" is happening right now? ->
