Totally agree with Spotter.
Several times I've seen a/c go up at 4000fpm climbing to 6000ft and on that basis clear them higher (say, FL130) in the anticipation that they will continue at something close to that ROC. In the process of sorting something else out I look back to I see it doing 2000 fpm !
IMHO, the angle of climb is what most ATCOs are looking for when they say expedite.
