Dear Heinrich,
In most planes we have, saturation is a bigger issue than resolution. Vibrations are the biggest culprit as g-forces from turn rarely exceed 2g while a rigid carbon frame with an unbalanced prop can easily generate 10g, and on helicopters we measured over 100g frame vibrations easily.
But since filtering is enabled, this saturation might not even be visible in the down-linked measurements so peak-tracking/saturation tests should be done with the internal sensor filtering off.
Which peak values do you measure at full power in turbulence? We always measure raw unfiltered values of much more than 4g and through filtering it then becomes 2-3g too.
