@robinsonmeyer What do you mean the recovery score is not a guide to injury risk? Is that an evidence backed claim? Overall your can pretty much adjust your training difficulty by your vitals and go well with that.

Once you get past basic mid-workout Strava HR/GPS/steps tracking, I’m increasingly unsure what the point of these devices are. Your sleep score can only surprise you on the downside. Your recovery score is not a reliable guide to injury risk. So what are we doing here?
Aakash Gupta@aakashgupta

You check your Apple Watch in the morning. Sleep score: 62. You decide it's going to be a foggy day. And then it is. A 2014 Colorado College study suggests the score itself causes the fog. 164 people walked into a lab. Researchers hooked them up to fake EEG equipment and told them the readout would show their REM percentage from the night before. Then they fabricated a number. Half the room was told 28.7%. Half was told 16.2%. The machine wasn't measuring anything. Participants took four cognitive tests. The Paced Auditory Serial Addition Test, where you add numbers spoken at increasing speed and hold your last sum in working memory while computing the next. And the Controlled Oral Word Association Task, where you generate as many words as you can starting with a single letter under time pressure. Both are gold-standard measures of attention and executive function used in clinical neurology. The 28.7% group outperformed the 16.2% group on both. Significantly. How rested participants actually felt that morning predicted nothing. The mechanism is mindset priming an executive resource. When you believe you slept well, you allocate cognitive effort more aggressively. You don't conserve. You don't pre-disengage. Belief about the resource changes how you spend it. Two control conditions ruled out demand characteristics. Participants weren't trying harder because they thought they should. Real measurable cognitive performance shifted with the number on the readout. The Apple Watch sleep score. The Oura ring readiness number. The morning ritual of checking either one is taxing the resource you're about to need. The performance gap from a fabricated REM percentage was larger than the gap from how rested participants actually felt. The number was louder than the night.

@TheZachMueller @ChrisSaysSo Maybe, maybe not, this post is just a further addition to the proof that AI systems dont have a moat. Its easy to switch, I do it all the time and thats a good thing.

I’ve been using Claude Code since July of 2025, and have been on the Max plan the entire time. There was a solid 6 months when Claude was fantastic. The models worked great. And things could be predicable. After 4.6 things started to change, and known behaviors started changing. That’s not bad, models change. The importance here is the model didn’t ~regress~ on my own workflows and integrated seamlessly-enough that it didn’t bother me. 4.7 has changed that. Ever since its release I have fought this model. On behavior. On knowledge. On ~laziness~ especially, something the prior models I found for my tasks had no such issues. This model is the first I cannot rely on. Yes, insert one should never rely on a 3rd party model, but for those of you working this industry you know we still do to some extent. This will be the only tweet I do this rant, but after 10 months of using Claude, I’m gone.

@Adonis_KI @_zeke1909 Geht auch einf schneller tbh, im taschenrechner gibste halt nur 250 und 365 ein und klickst ein vordefiniertes zeichen. Aber ok Grossgehirne schreiben ja auch lieber ganze Fragen statt 1-2 Stichworte bei einer suchanfrage einzugeben

In the end your main goal should be to sleep well everyday anyways. Until then you need to use the signals you have.

I‘ve been tracking my sleep for 10 y now and let me tell you that it indeed takes mental training to be able to cope with any kind of external assessment, but as soon as you have figured this out you can improve your life quality by adapting your daily load to your external score

I remember I attached my perceived life quality and mood to these scores but as soon as you‘ve detached them you can act upon it. Bad sleep quality? Give yourself rest, fuel well, take a nap. Great sleep quality? Go run a marathon (exaggerated).

@Domenik221001 @mainz05memes Der Großteil eurer Kunden freut sich doch eh erst ab dem CL-Viertelfinale überhaupt noch über Tore 💁🏻‍♂️ ihr seid nicht im Ansatz mit Fans von normalen Vereinen vergleichbar und würdet an dem, was man im Abstiegskampf für Emotionen hat, wahrscheinlich draufgehen.
