.1mm is theoretical, unless you have your own spoke threading machine. .2 is probably also.
you did not mention much to give any real world opinion.
in general, 5 speed 1mm-2mm less on the drive side.
6-7 speed, 2mm less on the drive side. The reason on all that is to let the spokes do much of the dishing work for you, one will end up with a wheel that provides for maximum adjustment later.
