Thank you your the excellent summary. The HR-issue with locking to the high values is very much annoying. But your quick fix seems to work. i will send an error report with screen shots to them. Thank you!

Just got my Active Watch 2 (AW2) yesterday and I'm somewhat disappointed with the Heart rate (HR)-measurement. During the night, the watch was able to record my heart rate once in 6h 40min which is not good.
When I initiate the manual resting HR-measurement, it always gives me nice curve with clear peak and valleys that correspond to the difference between the systolic and diastolic pressure in my arteries . Nevertheless, the device fails to give me a readout for 50-70% of the times I've used the Manual HR measurement.
If I put my AW2 on continuous measurement while being idle at home, it will most often give me a HR that is roughly two times faster real value (measured by feeling the pulse). That is, my normal rest pulse is around 43 BPM and my AW2 gives a number between 80 and 90 BPM.
Surprisingly, when I went for a run yesterday evening the pulse measurement seemed to be responsive as long as I was running or walking. In the figure below you can see the HR-measurement reacting to the 4 x sprint and a walk that I took in the end. I did not have a chest strap to compare the accuracy, but at least I'm satisfied with its responsiveness.
In the end of the work out, I ran two floors up (Stair sprint) before hitting my bed. As you can see, the HR-measurement went havoc right after I stopped moving (the arrow). Instead of following my decreasing HR, AW2 started creeping up to the 140 BPM until it came crushing down to the accurate value 65 BMP.
I'm surprised that measuring the rest HR can be so challenging for the device. Do you think this is something that could be improved with a software update?
