I concur, and actually called Cateye to discuss it when I first got the unit some months ago. At first, I thought there was something wrong with the unit, because I was used to the very accurate Polar approach to the calculation. That would be my only complaint regarding to the unit, but at least when I am pedaling I see an accurate cadence display, and get an accurate reading on max cadence attained, but the average cadence at the end of the ride is useless in my opiniion.
