It's twice as far from the part as outlines I use, though.  I've been
using 6/6 rules for silkscreen lately.

I set clearance gap to be whatever the line spacing rule is, unless
they're power pins (regulators, etc) in which case I use the "fat"
rules.  Sometimes I tweak them if I'm hand-etching the board, or to
avoid slivers between pads.

Mask is always 0.075mm gap (3 mil), which seems to be what all the
fabs have as a minimum.
