How to turn OFF VO2max estimates?

Interesting that you say it gives a reading 10-14 points low. With my Vivosport the VO2max figure it gives me is 'upsettingly low' and I can't believe it's anywhere near accurate, so I'm ignoring it. I thought there was a way to delete particular readings in Connect though, but I can't find it either online or in the mobile app (or on the watch). 14 points would be enough to take you all the way from very poor to elite. It spans the entire range, rendering the result utterly meaningless.

I've found the place where you can edit your VO2max. On the web version of Connect, click on your profile icon,
then account settings
user settings
then click the pencil icon next to VO2 and it lets you edit it.

I knew I'd seen it somewhere before.

Yes, you can manually set your VO2max in connect, but I am rather referring to the automatically generated VO2max, that is given after "15 minutes of intense walking" if you have activity monitoring activated. This VO2max is based on the fairly poor quality from the OHR and the GPS, obviously resulting in a too low metric. And it is added to my VO2max history in combination with the more accurate measurements from the F5. So looking at my VO2max development in connect, I get a zig-zag line rather than a more appropriate trend line.

My use case is all training sessions logged by help of the F5, and then in between training sessions I use the Vivosport just to track steps, calories, heartrate during the day (and I like the true up function), but I do NOT want it to give me a VO2max estimate, just because I happen to walk for fifteen minutes or more occasionally. Especially since it is so far off.

I would just like to disable VO2max estimates from the Vivosport, and keep the rest of the data.

Yes that would be a useful feature.

Here are two examples of how wrong it can go. My lab tested VO2max is ca 60, and the Fenix 5 gives me 55-59 depending upon weather conditions and GPS reception (accuracy in pace). On January 25th I used my Vivosport at home as I charged the F5. No activities recorded. I was preparing and having dinner with my family. Still a VO2max of 44 (the preciously logged and stored value in the VS) was sent to Connect. Today - trying to find a workaround - I started a cardio activity, selecting "outdoors" for GPS. I did put the VS in the window, to get GPS signal and had the activity run for 5 minutes. My thinking was, that only walking and running are supposed to generate VO2max estimates and if I occasionally would log a running session as "cardio outdoors" it would not generate a VO2max. But, it did. I did get a VO2max of 45 from having the VS in the window (not on my wrist) for five minutes.

This is obviously a bug. The enclosed picture is what my VO2max history looks like in Connect. The high 50s are correct. The mid 40s are just rubbish, and clutters my real VO2max trend line.

So, not only can you not disable the VO2max, it generates values out of nothing...ciq.forums.garmin.com/.../1450913.jpg

Yeah that's bad. I have no confidence in the VO2max reading from my Vivosport. I don't have any lab results to compare it with, but I doubt I'd be able to cycle 44 miles in a little over 3 hours if I had VO2max of 39, like my Vivosport thinks.
