• Without comparing to a BTHRM and without testing with much movement, the values given by the HRM seem to be a lot closer to reality. Having a resting pulse with the old algo of under 50 would be nice to have, but for me it is not exactly realistic :) So at least in the constraints of it being an optical sensor it now works much better. I had the chance to play around with a Garmin Fenix 7X which should have one of the best optical sensor available. That worked impressively well, but even that thing wasn't able to keep up with steep rises and falls in pulse rate during movement like an EEG based sensor does.
