You are missing the point that MSFS does not model, nor need
it for the vast majority of sensible users, the forced
(slewed) behavior of a 172 in the high flight levels be
real. Any real pilot, who knows the feel/behavior of a 172
class airplane near sea level, verses say 12,000 feet, and
who understands the aerodynamics involved and the effect of
limited HP in really rarefied air, need not be a "rocket
surgeon" to be able to accurately extrapolate.
