The flight parameters show the control wheels were desynchronised for two brief periods of 2 seconds and 5 seconds duration during the same period the control columns were desynchronised.
The force required to override either breakout mechanism is 50 lb.
OK, I stand corrected - that's different than some of the older Boeing aircraft.
