WatchOS changed VO2 max algorithm?

[Spindel]

Updated to 7.2 yesterday. Have taken one walk and one 8 km run today and have a abrupt jump up in the estimated VO2 max value for both (both at about the same lever)

Is there any documented change to the algorithm? The change isn’t ”natural” as I see it.

There is a thread with many of us that can't even get the stupid thing to give us a VO2 Max, no matter how many walks or runs we do outdoors. I have seen another thread where some have there measurements jumping all over the place, low to high to low

I find it depends on the exercise I did.

Score from running was 7 points higher than outdoor walk. Although perhaps it was incorrect or still calibrating. I think this is still learning, perhaps. And now that apple felt comfortable enough to roll it out officially enough to drive notifications, it may be more accurate.

We’ll see what happens as I keep feeding it data.

For me AWs VO2 max numbers have been consistent all the time either a slight upwards slope or slight downwards slope but no matter if I run or walk it's about the same with small variations. But as of WachOS 7.2 the value made a jump, but so far has stayed consistent at the higher level.

I was just wondering if there's been some tinkering from Apple on the calculation for the VO2 max value.

If the given value can be trusted is a different discussion. But I do think it is useful for your own relative development, you just have to take the absolute value with a grain of salt, but the sudden jump for me breaks my "trend" even if it seems to continue after the singularity.

EDIT:// Here's my trend

I need to learn more about this.
