Good egg: Thanks, that's exactly the sort of info I'm after.
Chevvron: Yes, exactly. The publicly available documents for the UK (for eg.) don't have hard numbers- they (the CAPs) stipulate they must be in the UTPs accepted by the CAA. But finding out what those hard numbers are within the actual UTPs is difficult.
Where I work, the regulator has recently stipulated hard numbers as minimums which have generated a lot of discussion.
