Maybe this is not true for the 3 chain engines.

Not the way I understand camshaft deviation.
Think of the relationship of the camshaft to the crankshaft.
The cam will be timed to the crank.
Lets say the Cam is off by 3 degrees of advance from that set point.
That would be 3 degrees of positive camshaft deviation.
So actuator kicked in or out you will still have 3 degrees of positive camshaft deviation from its proper timing relationship to the crankshaft.
The movement or advance of the cam when the Variocam actuator kicks in is a design feature of the system.
Deviation is not.
That's my current understanding of it.
