What real world mpg are you getting from your 1.2 TSI?

I'm pretty happy overall with the 1.2 TSI (2014) I bought recently, although I'm slightly disappointed with the mpg I'm getting so far. Obviously I know that the official figures are unrealistic and it would be a tall order to get 70mpg in extra urban driving in real road conditions. But when I tried it a few days ago on a few miles of dual carriageway @ 70, followed by a few more miles on a quiet A road @ 40-50 driving as smoothly as possible, I feel I should have got more than 51 mpg. In town driving, it was in the 30s.
That was running standard E10 unleaded and, to be fair, the town driving has been in short runs with cold starts. I have since tried using Super Unleaded and that seems to bump up the mpg marginally in town driving (not tried a longer trunk road run with SU yet).
I'm just wondering how this compares to the real world figures others get with this model of TSI?
When I took it for an interim service shortly after I bought it, the guys did mention that the diagnostics showed a slight misfire (so slight that I can't hear or feel any misfire, it drives very smoothly) and suggested that it may need new spark plugs. The service history shows no sign of any spark plug changes since new, so they're probably right on that and I'll look into changing them. But in the meantime, my mpg does seem way lower than I was expecting.
