My German Garmin tracks my sleep daily and I’ve never had a REM stage of sleep be 90 minutes.

    I don't know about your German (har har), but I'm not very confident in what my Garmin or any fitness watch detects on sleep. I got a Garmin to replace my FitBit, wore them both for a while, and saw they didn't have much consensus on sleep data.

    I don't think this tracking can be that accurate.

    Well after a cursory look online it seems OP was talking incorrectly.

    Studies show that sleep itself is segmented in 90 minute blocks with REM coming at the end. Rather than the REM section being 90 minutes.
