From the SHEED requirement of 2500A, you do not have a 3 degree path to the runway so the rate of descent is always going to be a bit higher than normal unless you have a rip roaring northerly which is sometimes the case. So you need the dunlops down and almost full flap before you leave SHEED. 737 can be flown down to short final before disconnecting automatics. Just set up the runway extension (2.85nm final) and Bob's your aunt!
