iOS 27.2 beta changed how Cardio Fitness (VO2 max) levels are calculated It still depends on age and sex, like before, but the boundaries between levels now appear to move smoothly with age instead of jumping at fixed age brackets. Mine went up

That sounds like a good change if the underlying estimate is stable. Age-bucket cutoffs can create weird cliff effects where nothing physiological changed, but the label did. Did the raw VO2 max value move too, or just the zone?

Just the zone. I didn't spot any changes in the VO2 max algorithm. Even the version is the same (4). BUT they added video-based assessment with the help of Apple Watch or AirPods as an HR tracker P.S. I love and use the Super Age app

Appreciate the detail, and glad you're using it. The smoother zone boundaries sound like the meaningful part here; if the raw VO2 max algo/version stayed put, that helps separate label changes from estimate changes.
