Hi,
I've noticed, that the HR measurements are sometimes completely wrong, see also below.
It's showing an average of 56 or 59, but I know that is wrong. My bicycle ergometer was showing HR of 70-80 (I am doing very mild traning these days).
I was using "other" activity.
It's not happening always, I had occasions, where the HR appeared to be correct.
Have other people observed the same ?
Regards,
Willi
