Average speeds do have a lot to do with the economy we achieve. True the mix of driving is important, but had a 'feel' for what you are doing, to get to the high figure, from your first post.
BTW, you are showing the OBC figures. Do you know how accurate it is from proving with brim to brim testing?
I also note you say 65 - 70mph, is that speedometer, or true speed?
The above two factors are important, particularly when others can get mpg envy.
On OBC figures, a reading of say 63mpg +/- 10% gives us a spread of 56.7mpg to 69.3mpg. Not uncommon to have that sort of tolerance band across OBC readouts, even in BMW cars.
