Best MPH for best MPG

RE: Best MPH for best MPG
I'm a mileage freak and have checked mileage for every fillup since buying the bike. Figures below assume windshield attached and no headwinds or tailwinds.
City: 47 mpg. nearly every time.
Highway, constant speeds: 50mph, ~60 mpg; 55-60mph, ~55mpg; 75-80mph, ~45
High-elevation, steep grades, slow speeds (e.g., CO): ~60mpg (also no power)
Best mileage: 63.5mpg (with windshield and 20-knot tailwind, averaging 50-55 mph)
Worst mileage (after installation of Thunderslide): 42mpg during a 575-mile, 75mph run down I-10 with a major headwind.
Average on last few trips in touring trim: ~54 mpg. We usually take backroads, moderate speeds. Rarely in a hurry, you know.

RE: Best MPH for best MPG
Just bought a '06 Road King and I got 59 mpg with wife on board. Mostly 55 mph but also was not trying to conserve the fuel. We were on two lane roads through a lot of small towns and quite a bit of traffic with some good cross winds. Was having problems with the gas I bought from a local conoco station(35 mpg) so I went to BP and paid for their 91 octane. Thats the ticket for me.

RE: Best MPH for best MPG
I agree that rpm is probably more important than mph in getting optimal mpg. That said, I don't ride with the idea of getting the best mpg. I like riding the twisties in second or third gear and taking it up to 80 mph on the superslabs. Sure, I don't get as high a mileage as I could (still between 40-43) but it's a lot more fun!
