Yesterday I swam 50 laps, so 1250 m, but Race S fw 2.39. 44 only recorded 1075 m. It lost 7 laps! The first 20 laps I did freestyle + backstroke and the last 30 only freestyle (see image below). At the end of every 25 m I pressed the down button to track the lap.

People can buy Suunto because it’s very nice but if it doesn’t do the main job (recording the activity correctly), they will go and buy other sports watches. Thanks.
