As 1261 says, if you have requirements on final approach, if you tell us with plenty of time, we can do something about it (eg: 777-300s and some 737s request 170kts on final).
I am a little concerned about MrBig's comment about being advised to cheat and reduce at 5 miles. In no way am I telling people how to fly jets or amI crusising for a flight, but reducing speed 1 miles early without telling the radar guy can be a major pain in the a$$ (wake vortex separation comes to mind).
