I do know that my worn slots measured 1.98 mm at the bottom and range from 2.16 to 2.26mm at the top - giving an out of vertical of from 0.18 to 0.28 mm.  The specs say a maximum feeler gauge between an inserted apex seal and wall is given as 0.15mm, I could insert an 0.18 mm feeler in some and an  0.15mm in all.   I don't think I would feel comfortable flying with a rotary in that shape (anymore {:>)).  Putting them in an auto is a different story - if it breaks - park on side of the road rather than strain the eyeballs looking for an airpatch.

 Ken I screwed up on reporting the  rotor slot width, it should be 2.17 to 2.26mm not 2.017 to 2.026mm

Georges,
    Are these numbers in reference to the apex seal slot taper from
the bottom of slot (2.017 mm) to the top of slot (2.026 mm) which
is a taper of (.009 mm) or about 3.54 thousands here in the 48 ??

 Hi! Ken
Do you you cut on a taper, where does your taper start? or do you just skim 0.015" off each side for a total of 0.030". I just measured the two rotors that were in a "GOOD" running 92 13b NA & got a reading of 0.017 to 0.026mm, I guess they are toast.
