and the day the pilots idea of expedite doesn't meet your requirements you will not have a leg to stand on
Hence when I said
correct, which is why I will only do it with the a/c on headings (probably converging) and I can then 'tweak' one if the expedite isn't expeditious enough.
I have a leg to stand on
In your capacity as an upper air sector controller, you, I would hope, should have no need for a faster climb rate. In the TMA world where a/c are constantly having to achieve level changes to get in/out of the 6 airports with SID's/STAR's that cross each other, expedite is an often used and very useful term. As somebody else has mentioned in this thread, we are even offered a 'good rate' on climbout by some crews and as was also pointed out the word expedite is in CAP 413 and therefore acceptable.
