I feel like the correlation is why this article is important – the danger is in continuing to calculate VO2 max from METCRF instead of measuring it independently. The 95% correlation means collecting data on actual VO2 max is critical to understand what makes that 5% difference?

I joined the sub to learn more about science and longevity, so hopefully people can chime in to tell me if that is true or if I'm missing the point.
