» Technically, it could get a little involved: If you have n observations, of which m may be less than 10% of the (n-m) rest of observations, then identifying those m observations is computationally very different from anything else we usually encounter in BE. The approach can rightfully be called a kind of m'th order jackknife but we do not need to traverse all permutations to find the m observations.

Correct. Little bit tricky.

» I think it is a brave and much needed leap forward on the part of the regulators that they allow it. Dasatinib has caused lots of headaches and peptic ulcers at Sponsors and CROs globally. Those days may be gone. :-)

Yep. What surprises me is the footnote (as in many product-specific guidances of the EMA).
Well, we know that the CHMP’s PKWP reviewed a lot of studies. The ones I’m aware of showed – without an exception – highly variable Cmax.
