There's a mean decrease in acceleration due to gravity of only 0.3086 x 10-3 cm/s2 per meter of altitude. That's minute, and means that your overall figure of 0.1g is probably right. If we're being that technically precise, gravity varies from place to place due not only to altitude, but also to subsurface mass distribution; and centrifugal force varies with latitude.

Then again, what method is used for the weighing? A 45g pan weight would obviate any such problem. If in doubt, why not simply take emergency add-on material (e.g. a pin).
