If I may make an input regarding CONF's statement...

The manual (hand flown) stall QTG's for the simulator are specified to be done in Direct Law with a specific stop manual trim speed. As you decelerate below this speed, without benefit of trim, SS movements tend to be exaggerated to some extent in both directions to maintain a stable flightpath, with varying levels of spring force to deal with.

If the entry is done in Alternate Law, as the rate of airspeed decay progressively increases with the drag buildup, the autotrim input essentially outpaces any necessary SS commands and allows a more 'relaxed' SS input, with less awareness of any spring force.

I think this what he is getting at, but I could be wrong, and don't want to speak for him.

(CONF: Thanks for the reference to the A33Zab post)
