So reporting approx half the actual rate @HughB? Half the actual rate is actually better than I expected for while running (although looking back you said all over the place), and is what I am still sometimes seeing when absolutely still.
Seems to happen when the heart goes over a certain rate, because I was consistently getting readings in the 40s when my heart was going over 90bpm but I get an accurate reading when it is in the 70s.
