I have always dealt with dimensions called out as TYP or (x)PLCS by measuring each occurence of the characteristic and then recording on the inspection report (1st article or otherwise) the highest and lowest reading I obtained(e.g. .0007 / .0016), or in the case of a unilateral tolerance the highest reading obtained followed by MAX (e.g. .0016 MAX). I can't cite any sort of standard to support this practice, it's just the way I've always done it and no one has ever squawked whether it's been in defense/aerospace, automotive, medical device, or semiconductor fabricatiion equipment and regardless of whether it's been machining, fabrication, plastic molding, or powdwer metallurgy.
Now if the customer or end user really wants to drown in information, we do periodic capability studies on all features designated by our customers as key characteristics and will happily provide them with that documentation.
