Mm-hmm.

But I'm not proposing that everybody should like get someone like me to do that or even have the need to do that.

It's just understand that there are limitations.

HRV is not nearly as robust of a metric for telling you something about your physiology as something like VO2 max.

Like VO2 max I'd put up there as like a metric of like, okay, this is kind of like a true metric of like overall like wellness and overall like fitness.

HRV is not like that.

It just doesn't operate like that.

And it's not a normative-based metric either.

It's like we technically do have norms because we've done so many studies to where we know where people typically fall.

But we also know that because of the other influencers, genetics, age, sex, that if you don't fall within that normative range, it actually doesn't tell us anything about your overall level of health and wellness.

It's like if you know that, hey, for males aged –

35 to 40, the mean RMSSD value is 56 milliseconds.

And, you know, the standard deviation is 10 and my HRB is 25.

So therefore I know I fall multiple standard deviations outside of the mean.

And so therefore I must be unhealthy.

It's just not, it's not the case.

We don't have enough evidence to suggest that.

So it does require a little bit of nuance.

And I think that it's best used when you have someone, and we can bias, like me, who can inform you as to what it means.

But HRV is best used this way.
