I already answered above that he was getting VO2 max numbers from a watch in another thread. That probably indicates a GPS watch. Are you aware of a watch that estimates VO2 max without a GPS?
Studies have shown that smartwatches are accurate in measuring VO2 Max
They don't measure, they estimate based on performances. Equivalent performances can be had by a pretty big range of VO2 maxes. My GF was tested multiple times in college to have around the highest ever recorded for a woman. She was not that fast a runner.
