The low HR (29) I've observed while sleeping with this watch
isn't as low as has been observed in a clinical setting nor
what I've captured with my Polar watch\HRM chest strap. This
is why I asked the question at the top of this thread. For me
this is a real number in fact it's not the lowest I've seen,
only the lowest this watch can capture, even after resetting
the watch I consistently get 29 while at sleep. Not everyone
falls within the range of normality, there are exceptions and
I'm one of them. I'm sure there are others.
