VO2 Max readings off a cliff with new watch
I found a thread here from a year ago about this same issue, and it seems to still be a problem.
I had a Series 4 for years and was very excited to see my Vo2 readings increase as I ran everyday. I was up to 40 before I sadly lost my watch in an accident. I went about three months with no watch, continued to run everyday just the same, no drastic changes to my fitness or health routine.
About a week ago I got a new watch, the Ultra. Went to record my first run and was shocked when my Vo2 reading was 24! This is laughable! I absolutely refuse to believe this is a correct measurement. It is just so insanely frustrating that there is no fix for this glaring bug in Apple's product.
