Stackup calculations (X min / X max.) 3

An “adjusted” (positional tolerance-wise Ø3mm instead of 0 at LMC) picture from ASME standard. (7-17/2009)
Question: What would be X min. and X MAX. for the case shown?

I mean, what's the definition of "perfect form" here? If the hole tolerance tells me that it applies only when a Ø19+0.5/-0 shaft is at LMC (and therefore "perfect form"), shouldn't that mean only when you've got a perfectly straight Ø19 shaft in which the upper limit doesn't come into play?

The perfect form limitation only applies at MMC unless the feature itself has a geometric tolerance that applies at LMC. Since the outer diameter has no geometric tolerance applied, then its perfect form is at MMC.
