Zenza Bronica EC focusing woes

If you know what's wrong with this camera, please comment below.

Each photo focused on the center circle in the test chart.

Mirror was locked up before each shot.

Aperture left to right f/2.8, f/5.6 & f/16

 

Camera seems to be focusing behind the target. I suspect an issue with the registration distance to the focusing screen.
