What you should look at is the overall mileage, over a longish period. I've had my Zed from new and the computer has never been reset other than when I changed the battery. After it settled down I've found that over 13,000 miles its averaged 27.0 and that includes a bit of every type of motoring. One thing of note though is that I rarely go above 4k revs and always stick very closely to the speed limits. Caroline's roadster which we bought in 2010 is averaging a measly 21.2 over 5,000 miles but her trip to work and back is in heavy traffic...I think she uses more revs than me as well
