Hello. When my rate rate is low (<55bpm) it will often incorrectly register as double. For example, sitting inactive and measuring my heart rate three times using the Heart Rate Glance might measure it as 52, 104, 52. It clearly isn't 104, it's still 52, but it cannot correct profile the beat.
The watch is a snug fit. Any suggestions? I get the same proem when the heart rate is sampled automatically at timed intervals.
