Hello RetiredF4,
This can be a major catch !!! Your question is indeed very important!!!
I still don't have an answer to my question, which is somewhat along the lines of yours:
"Is the actuating of the control surfaces proportional to the duration of a control SS command", which could also be a contributor to the amplifying of control surface action, if the perception of the control surface action by the PF is delayed.

If the SS input to the flightcontrols, in this case to the elevators (and the THS???) is modulated according to speed, what speed source is used and is that a gradual change or a change of lets say 2 or three different datum values?
I think this question is very important, as we see a drastic drop of IAS after AP dropout while PF was (mis)handling the SS. If this new "false speed" changed the modulation of the SS input to the extreme low speed regime (wich at that time was not cosistant with the real speed), then the SS inputs of the PF would suddenly cause much greater flightcontrol deflections than moments before. It would explain part of the initial SS control problems and if THS travel is speed dependent as well we should look into THS travel to NU in relation to later (when speeds where valid again)THS travel ND also.
