Oura's getting sued over how accurate their sleep staging actually is. Got me curious so I went poking at my own Garmin data this weekend... turns out my sleep stages have been sitting in a file on my computer this whole time. Every minute of every night. Never once looked at them lol. So I had Claude build the sleep screen out of it - time asleep, the stage chart across the whole night, deep/light/REM, plus HRV, resting HR and skin temp. Then I had it check one more thing across all 54 nights I've got. My deep sleep ranged from 5% to 37%. My REM from 3% to 33%. Same watch, same wrist, same guy. Every one of these devices is guessing your stages from heart rate, movement and temperature, Garmin included. So trend the score week to week and hold the deep/REM split loosely. If you've already got your Garmin connected, this data is on your machine right now 🤓 Full guide and prompt here: Oura Sleep Prompt Build this into your Athlete OS so it lands every morning! Kevin
