Hmm, good question. Still, it might be possible that rapid, very small
repositions could be imperceptible. I was just taking a wild shot at
this one.

I read somewhere that the F-16 is so unstable that a human
can't fly it without the computer control. I'd think that
means it makes corrections faster than a human can, but it's
making corrections to a known airframe, I guess. I'd think
they'd want the response time of an autopilot to be fairly
slow so it doesn't do abrupt stuff - but then it really
wouldn't be able to handle weather.

Yes, this is true of all modern fighters.

If you watch movies of a takeoff or landing, you will notice the ailerons and
horizontal stabilizers fluttering all over the place in what is pretty much
straight flight.
