(and was wondering why you > cared, but assuming "each to their own") I am at least as much worried that the metric user can jog .2mm's and get .2mm's. Both according to the DRO, and a metric dial indicator, which I don't have one of. On this side of the pond, its inches or get out a calculator. But if its machine units, the metric user might want to up the size of that string of setp's just to get a minimum jog that isn't polishing the hubble mirror to the wrong curve. :) But that still doesn't make a multilabel work.
