Hi,
I wanted to adjust the HR zones from the default to the Karvonen ones, as they seem more realistic for me. On doing this i discovered that even though this change boosted time in zone 4 (less zone 3) for near identical rides, it halved the RE (relative effort).
On inspection just the act of switching the HR zones to custom, but setting the zone boundaries to those calculated by the 'auto' feature had the same effect. (Forcing a recalculation by switching ride type and back)
I want to carry on getting the consistent RE so I can look at the historical 'fitness' (aka training load) data, so I shall carry on with the Auto zones. To me this can only be a bug, unless there is something I am missing?
