mpg/fuelling

I filled the tank with E10 close to the brim and found that after approx 185 miles the needle was down to just a fraction under 1/4 tank. Local driving, with mild weather. The consumption has been down like this before, but only in really cold weather and when the engine was not running at its best.
Filled the tank with E5 (Momentum) and after 258 mls (again, local driving) the fuel gauge was around half a tank (I don't think it has ever been as good as this even in summer). I calculated 44.38mpg. The gauge certainly seemed to be going down slowly...
Filled again around half a tank with Sainsbury's E5 (never used it before) and getting down to near half a tank and heading for 220 miles, which would equate to 37.9 mpg.
On the old regular fuel I usually got around 32 mpg with local driving and I think the best I've had on a run is 42 mpg. I've used super grades before, like BP Ultimate and Shell V-Power and never got this mpg. My 9n is a 1.4 auto.
Firstly, I'm wondering how this is even possible, and if something is going on with short-term fuelling after the E10 fill, which seemed to increase thirst.
