On a whim I decided to use the FoCal target outside. Printed three of them and lined them up on a wall. Noticed that my lenses would not focus on the target. Live View focused ok, but using the viewfinder was a no-go.

Probably not it, but what about the reflectivity of the paper? Distance to target?
