This is a very valid question I have received recently on X, after I had highlighted how absolute values of HRV tell us very little about our health. Below are some of my thoughts. I wouldn't say readiness to train can be provided with HRV alone, as HRV is missing key aspects of "physical activity readiness", e.g. muscle soreness.
On one hand, I really love the advent of having immediate feedback on some of our health data. On the other... There's definitely a risk of outsourcing our connection to how we intrinsically feel & using the numbers as the "be-all end-all". I've personally found great benefit in having both available!
And yeah, as far as your tweet, you really highlighted the trouble in research illiterate people online making sweeping claims about health & wellness. People are complex creatures... You can't look at a singular measurement & decide that's the definitive metric we should be monitoring & you're doomed if you aren't in the "ideal" range.
