Not to beat a dead horse or anything... The only thing I can think of is an external table for wireless tools to look up the card somehow. That way you could map +-63 to something meaningful on a per-card basis. Most of the cards I see claim between 10-16 as the max power they will put out. This might add too much needless crap though.

"You are in a maze of twisty standards all different".

While we are on the subject. It appears that the power level "floats" if it is not explicitly set, is this correct? Is there a way to return to "floating" once you set the power? If this is in some docs somewhere just flame, and I'll look again. :)
