I would posit that the same problem exists while attempting to
hold the horizon stable while bringing down the celestial object
using a regular sextant. The addition of an electronic averager
would iron out the bumps. And no horizon needed!
If you want an example of how hard it is to achieve exact levelness, I suggest downloading the free smart phone app "Theodolite" Using just the basic capabilities of a smartphone it gives an indication of how level you are holding your phone in both the fore and aft and sideways directions. And how those readings bounce around as you attempt to do your best possible job of holding your phone steady.
