Good pilots fly a stabilized approach that is a constant airspeed and thus constant rate of descent from the outer marker to the flare. The theory is that a stabilized approach reduces the pilot's workload as they're getting closer to the ground: If the aircraft is configured for landing and all the checklists have been completed all the pilot has to do is gently nudge the controls to keep the plane going where they want it, and they can concentrate all of their attention on a nice, safe, smooth landing. If you don't have one - you go-around.
