I have selected to show my Heart Rate data as percentage of max, rather than BPM, but it doesn't show as such at all. I can manually change it on the Stats page of any activity, but the splits, and the graph always show in BPM. Is there a way to change this? I train on HR percentages, and its a pain to have to translate all the time from BPM to percentage.
There appears to be some confusion in Garmin Connect re HRR (Heart Rate Reserve) and MHR (Max Heart Rate). In "Settings" the values are for HRR (if you have entered a resting heart rate). In the Activities windows, one heart rate option is labelled "% Max HR" but I think this actually uses the HRR zones.
