Nope no camera deformer, but converting the trace to a mospline will solve my blues.

Ah, finally found it, had to offset the hand and position it a bit better, zero out everything and use the mirror tool. Don't forget to turn of skinning and resetting binding pose for the clone. It all works now.
 

 

Found one possible solution: export as alembic and re-import. Perhaps there's a more elegant solution.

Updated the RS install, problems begone

I posted the quetion at Cineversity too, got an answer from Dr Sassi. For the record:
 
"My understanding is – that the joints that drive the points for PSD must be in the Driver list. With that, the resulting Joint-pose is part of the recorded PSD result.
With two joints producing pose one and then in pose two, that would result in the need for a definition of each pose, as the angle for the Shoulder changes."
 
I now have a PSD correction on the elbow with the shoulder and the forearm set as the driver and (very important) the PSD interpolation mode set to Global Strength in stead of Per Joint. "This mode will apply a deformation percentage based on the global delta variations of all the joints. All their delta values are averaged as a common strength value" the manual says.

Found a better explanation by CGDreams, i susspect something is off with the symmetrie of my mesh:
