Nice Depiction of the stick movements Grity!
Somehow I had missed this the first time.
Earlier I had noticed a ~2 second period between stick reversals in the BEA data. For a transport sized aircraft, this is very rapid. Mayonnaise stirring for sure when you consider the scale of what is happening with the aircraft. And look at the amplitudes of lateral stick travel!.
PF had to be all tensed up with his mitt firmly around the stick. Probably with his arm not properly supported as well. Hard to keep from pulling a stick back inadvertently under those conditions. (But keep in mind I've never sat in an Airbus Cockpit).
