@sky-runner said in Auto-detected lactate threshold is horribly wrong:
So clearly at least something isn’t right
No, it is an obvious bug somewhere, but not something I’ve encountered with my Race S and the Android version of the Suunto app. Here is the latest aerobic number:

And the whole week has been spot on, reflecting coming back after a small injury, with dropping aerobic conditioning and a few days of unbearable temperatures followed by rainy ones. Trying to do ‘easy’ trail runs of around one hour (except the last one which was a village run of 32 minutes):
“Measured” “Aerobic threshold”
140 bpm 20.1C–20.9C ZS Green 67% Yellow 33%
146 bpm 26.4C–28.6C ZS Green 74% Yellow 26%
144 bpm 16.1C–16.0C ZS Green 81% Yellow 19%
141 bpm 14.9C–14.7C ZS Green 86% Yellow 14%
By the way, at least with the Race S there is no need to activate the S+ ZoneSense app in the watch. Everything is native as long as a HR strap is in use. The app only gives a nice graphical view of the effort level.
