WEEEEEELLLLLL! Maybe, but I work a larger relatively low traffic density group of sectors where you see all the bangs well in advance and "do" something early. If our guys say "expedite" it means they didn't spot something 10 minutes ago when they should have and no longer have room for a requirement and maybe a vector might no longer do the job.
I would prefer to say "reach F350 by 20 miles Gripdicken" for the same effect, if the aeroplane can't do it that day you find out straight away (mostly.)
