Thanks for taking the time to do that.
My daily commute includes 20km of 110kph motorway.
Driving that leg at 100, or even 90kph only adds a few minutes to my travel time and aids my fuel consumption.
If I'm on an extended motorway trip (hundreds of kilometres), that extra time can become a problem (worse if I've got passengers) and I usually drive closer to 110kph (averaged between uphill and down).
The increased fuel economy from no stop/start driving more than compensates for the lower fuel economy of the higher speed.
