    Cg, that callout means that the feature profile tolerance is Unequally disposed. Huh?
    That just means that the U after the 9.0 tolerance allows the feature to ADD material by 7.0. and though it's not in your FCF, the removal of material from the feature is simply 7.0 subtracted from the TOTAL tolerance of 9.0......therefore material can be removed by 2.0
