I have read that past Garmin watches have accuracy problems for 24/7 wear due to the varying sample rates for the Elevate OHR. The problem as I understand it is that you could go from sitting to standing and walking around and the watch would register a very low HR as the 24/7 power levels perhaps do not include filtering for movement. Does anyone understand this issue and know whether the Gen3 Elevate handles it better? I also wonder if poor handling of non-workout HR would affect the Body Battery.
