So I noticed this in the earlier email that you sent on the topic but
since I'm traveling and rather busy I didn't get around to comment.
But this bothers me. from 60 to 80 to 100 bar the z_factor goes UP!
That just seems wrong. Maybe there's something in the physics that I don't
get that makes this a magic range, but still... this at least needs an
explanation.
