It's at the same point in my commute, so that's a consistent mark. The best approach, that loses the least mpg, is the old "slowest speed in top gear". If I start the hill at 25 mph in 5th gear (1000 rpm), hold 80-85% LOD, I accelerate to the 45 speed limit at the top, with the least mpg lost. Other gears, higher starting speed, lower LOD, all give worse results.
I also find this to be true.

It is more easily seen with sensetive instrumentation. (MPGuino in my case)
