I've used an Ionic for a number of years before purchasing the Sense on 30 October. The Ionic tracked swimming laps very well. Unfortunately the Sense tracks the lap so poorly that it cannot be used in swim training. The table below shows that it is very inconsistent. Does anyone else experience a similar problem?
