OK, once again; this has been addressed before and either you missed it or you're ignoring it because it doesn't fit with your theory.

The FDR records position of *both* the *rudder* and the *Rudder pedals*

The FDR positions from the accident of *both* the Rudder and rudder pedals agree.

The Yaw Damper acts through an averaging mechanism which prevents yaw damper movements from moving the rudder pedals.

If the yaw damper moved the rudder, the pedals would not have moved

The rudder pedals moved.

It measures and records *both*

Sorry to keep repeating, but this has all been posted before. How many more times does this have to be repeated before you read what is being posted?
