I'm always curious about the desk jockeys that come up with this B.S. The same with fuel leagues. You launch off, engage VNAV and autopilot at 1000'; crz at optimum; descend in VNAV via a STAR or radar; complete a CDA in low drag and land; taxi-in on 1 engine and shutdown. What more can you do? Some companies don't like short visual approaches; some guys get lucky with short-cuts, some don't; some guys get straight in's due to wind, other have to go the long way round for the reciprocal; some guys get the full STAR due time of day, others at night get a direct as STD. It's all such a lottery that to attach some magical skill to fuel saving is not honest. It's easier to identify those who are consistently on the high side rather than give Oscars to those running on fumes.
