The difference is the slow response of the mechanical ASI damps the transients, whereas an electronic device can respond fast enough to track them.

OK, understood, thank you. This generates a new question from me (sorry if this is turning out to be a lesson in instrumentation design...):

Can you slow down the response of your electronic system so that it behaves similarly to your mechanical ASI, or does this bring on poorer performance elsewhere?
