I'm just going off of the fantasy world that is sim land. And I don't know if it applies to all sims or not. But the ones my company has use upsdated data from real flights to best simulate flight characteristics of the aircraft for things below FL250 IIRC. Anything above that just goes by how the programmers put all the 1's and 0's in place, anyway. At least, from what an instructor told me, with that being said......
The high altitude stall is VERY interesting. It's quite the opposite from the low altitude where things can happen quickly for recovery, on a relative scale at least. It's can seem like an eternity as the aircraft is losing thousands of feet to recover airspeed at a slow rate while the aircraft has the slippery feel from the high altitude.
