Not clever algorithms

- Vo2 Max: work for Walk, running, trail running. For walk activity, no matter how easy the exercise is you'll get a value (usually totally wrong), meanwhile for running and trail running, you'll get a value only if you run at least 10 minutes. Two problems with this: if you register a walk, it will ruin your previous running or trail running value. The second problem, I do a lot of outdoor high cardio in the wild, I alternate walk / run but I always run less than 10 minutes, so I don't get any Vo2 Max value out of it, unless I register it as walk (which is not appropriate).

- Training status: do not seem to take into account your exercise if you don't register an activity manually, which is dumb because I do a lot of stuff all day long.

- HRV: The watch is warning me lately that my sleep HRV is unbalanced, while my HRV is going up, I get it it's different than my previous past base status, but it should be seen as a positive sign to have my HRV going up (as far as I understand it).

- Sleep tracking score, imo is not very accurate and does not reflect how I feel (hopefully better with the new update).

    Yeah, I have to admit that for me the VO2Max/Training Status mechanics seem extremely unhelpful.

    I posted accidentally in the wrong sub-forum, but for me I (for example) have no "low aerobic" exercise recorded at all (literally, it's 0), presumably partly because the "auto-detected" walking activities I have don't seem to count.

    (There's a compounding issue for me that the Activity Zones stuff seems to be completely incorrect for me - after more than a month of wearing my 255, it still seems to think that my Max Heart Rate is low enough that I can be in Zone 5 for *a whole hour* of running, which shouldn't be physiologically possible.)

    Why don't you set a more suitable max HR, then?
    I have been missing "high aerobic" completely at times. I think it is correct.

    Well... because it's on autodetect Max HR, and I sort of expect that to work? Isn't the point of having a device like this that it should be at least half-way good at figuring out where my Max HR and other things should be from measuring my performance? Even when I tried doing exercises at a low pace that it *suggested* should give me "low aerobic" points, they didn't give me any, and there was also no change to my predicted Max HR (even though the exercise felt very easy - very zone 2 on the border of zone 1 - to me, which, again should be something the expensive fitness tracker should be able to pick up on).
