The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
so I think we can look at HRV in a more granular daily basis just kind of say am I going the right direction and that's probably more of a utility than a great predictor of you know something and we can look at those daily changes to help us make more informed decisions we can't do that with V2 Max or with you know more invasive tests so it it's a more uh you know narrow data point but it gives us something we can use more actionably than these longer term tests I think are better actual measures of outcome
like we use V2 and we use uh those sorts of output measures as are we going the right direction and we have some prognostic value specifically from them we use HRV to say you know are we more likely to be making improvements on the short term or are we heading the wrong direction where if we keep doing that for a long period of time we're going to either see the benefit or the cost depend which direction we're going so I think they're different

The reason why people like HRV more is because it is far more stable. It is also like resting heart rate non-specific. So you don't know what's happening. But that variability that you're mentioning that Ben talked about earlier, that's also the benefit once you establish somebody's standard deviation. What do they normally fluctuate? Right. Some people are going to be really neurologically or nervous system going to be super stable. Some people's nervous system is really unstable. That itself is a marker. How wide you range on your daily HRV is incredibly telling to what's going on in your system. Because of that, that sensitivity, I can see things happening really quickly.
