Guy (and other ATC types) it might be helpful if we were told on entry that 300 knots was good (or 270..whatever) along with track miles to tdown. Most guys won't do 300 fpm if they know they need 1500fpm to make it. I always give 1000 fpm but I know many do less so they don't get low burning fuel.
It won't take long for everyone to do what you need if you tell them the track miles remaining. Or, conversly, with each new guy telling him 1000 fpm or more (which seems to be happening now with some controllers). We're like dogs--tell 'em enough times, till it becomes habit, and you'll get it everytime
