The best thing would to be get a scan gauge or Torque pro for your phone and set up a custom display that shows your throttle percentage, manifold vacuum etc. The lighter you accelerate and the sooner you lift off the fuel and the steadier you keep your manifold vacuum the better economy you'll see.
I have trouble winding all the way out to the shift light, but I'm beginning to think that by shifting too early I'm making my fuel mileage worse by spooling the turbo instead of relying on the displacement.
I did one time shift it at 6000 RPM in 1st gear to 2nd gear.
I would shift it by the shift light, I would say if youre shifting at low RPMS into higher gears, and keeping the RMPS really low, that the car would 'shudder'.
probably would be have to be below 1000 RMPS or something,
that being said it redlines at about 7000 RPMs, but doing the shift intervals on my gauge, I was able to do 80 MPH uphills, pass people etc.
but if I wanted to try for top speed I probably would shift above when the shift light would want me to shift.
55 MPH is fast enough for me though.
no idea if that would make it worse, but with a full tank it estimates 580 miles on my display. havent got a chance to try and see how correct it is, really hoping I get 50 MPGs, that would be awesome.

Your right foot will be the bulk of determining your MPG.
Average V and Vdt (AKA: Your Right Foot), plus stops and slows(signals/signs), and road grade changes makes the center of the curve.
Everything else you are working the tails of the curve, _far_ tails.
So without looking at those things as well... MPG comparison is silly to do. (remember the UK has a larger "Imperial gallon" so pay attention to who/where they are). If I lived in ANYWHERE Nebraska, MPG averages will look amazing compared to someone in San Francisco. Also, my grandpa ANYWHERE will have MPG averages that look amazing compared to a 17yo in Nebraska. Back road commuter with long stretches of slower steady driving on thinly used County roads will trounce a urban commuter traversing a mix of interstates, state, and local/city roads every day of the week.
Can't imagine why Ford would do guess work on the shift light, they want you to see the best they can deliver so can't go wrong much using it... but by far it's more important how you get to and from that shift light.
