I'm just citing the SID readout. I was hoping it would be inaccurate... ;) In all fairness, though, I have noticed the behaviour of the readout based on what I do. Periodically, I clear it and have arrived at a kind of "average" after an extended period of time, say 2-3 months. Finals include: 12.3, 13.4, 14.6, and so far (being really good in the last little while) 11.9 city/hwy combined. I guess I'll have to get used to it! Thanks.
