when I am not doing arms movements, vivoactive 4S considers that I am resting. example: when I use swimming board.I find that quite strange as watch includes pool distance, it should notice when i Change direction.
Other case: when I am doing the flow (push underwater) at each line for backstrocke / breastrocke, a few seconds are often considered as rest
sometimes watch considers I am doing 100m in 35second - this is simple impossible. Is there a way to collect accurate data?
