Apple Health VO2 Max

I had fairly stable VO2 Max readings for 2 years and then as of Nov. 20, 2022, it dropped precipitously (10 points or more) and has remained there for the past 3 months. My workout of walking 5-6 miles a day has been unchanged over this time, and I have no significant changes in my general health either. Was there an algorithm change by Apple or something in a release that would explain this?
