:Even with SA, much more accurate numbers could be obtained by averaging
:several measurements. I think that the speed at which the earth's
:plates move is slow enough to get a good average measurement (except
:during an earthquake, of course!).

No, you can't just average several measurements w/ SA on and expect
to get any improvement. SA isn't just 'noise', it's like a
drunken walker. All you get when you average several measurements
is the location of the drunk.
