Just excuse me for asking if I've understood that comment- I'm sometimes hard of reading...

You are saying you were flying a piece of kit around in a presumably vibrating aircraft, presumably in turbulence, and nevertheless it was still measuring "g" to an accuracy of one in a million ...If that was the case colour me very very impressed..in simple terms how the heck did it do that? ( simple explanation or a suitable link to one will do)
