Turbulence doesn't cause left/right rolls at the exact same roll rate.
Turbulence doesn't cause the elevators(stick) to go nose up/nose down.
Turbulence doesn't cause the rudder to go left/right.
Tough day but cycling the controls back and forth doesn't help.
Of course you would have done much better wouldn't you misd-agin? The controls would hardly have moved!
Personally I though the guys/girls did a great job, but like you I was not in the airplane, so I have no idea what inputs were called for, or what winds the aircraft was actually experiencing! Analyzing the control deflections, and taking up the role of a mickey mouse investigator with your infinite wisdom of what control deflections are caused by turbulence, and which ones aren't, doesn't really answer the question.
I won't ask what you are rated on.
