What do you expect from a pilot when you tell him to "expedite through FL80" ? Do you have his load information/fuel on board/engine perfomance charts in front of you? My point is, if you have traffic at FL70 and you need the guy to climb above, then do a little maths...tell him 2000fpm until FL80, or to cross FL80 in 2 minutes, the term expedite means something different to every pilot, and the day the pilots idea of expedite doesn't meet your requirements you will not have a leg to stand on.
