On Bangle 1 I came to the conclusion that confidence was a waste of time and it was better ignored and heart rate averaged
My impression is exactly opposite right now. Should have a real statistic by tomoorow. But it seems HR is really good when confidence is high (>90) and way off with low confidence which would make any averages useless. I got this impression from looking on BT HRM which show all relevant values.
If you look at the first 4 rows in the screenshot. Heart rate 99 - confidence 40, then confidence is 0 for the next 8 readings but most were close to 100 bpm.
