That's what I thought. I've never had a lot of luck with the calibration function on my scangauge. I'd adjust it, the mileage would swing in one direction. I'd adjust it back the other way a tad, and the mileage would swing in that direction. I used to calibrate instruments for a living, and the scangauge showed me all the signs of having too coarse a level of granularity to do any meaningful calibration. So I left the calibration alone, and now I treat the readings as a relative measure.
I would not suggest that anyone seriously use a scangauge as a speedometer.
