Deviation in Recorded Total Time

For some training sessions, the RPE does not match the calculated load.

I am not sure what is causing this, but could it be that the recorded time in the HR-zones does not correspond to the time in PACE-zones.

Would it be better in the settings to prefer “Pace,HR,Power” instead of “HR,Pace,Power” (at least for swimming (because the heart rate cannot always be measured accurately)?

You can have a high load, and low RPE, or vice versa. They are not directly related.

I don‘t know why your moving time doesn‘t match your time in zones. I could imagine that there were missing records (e.g. heartrate not recorded) or there were breaks which still counted as moving time. Which device do you use for recording?
