REM Sleep Accuracy

Is the sleep, particularly the REM sleep, inaccurate for anyone else on the FR 965? I wore a whoop for about a year and was averaging 1.5-2 hours of REM sleep. On my garmin I only get like 17min - 45min of REM.

I guess I technically don't know if whoop was accurate. However I can't image getting 17-45 min of REM sleep, according to my garmin, is right. I certainly don't feel as if I am getting that low of REM

Sleep tracking accuracy on all consumer devices is very low.

Sleeptracking is a marketing feature. They call it ‘advanced sleep monitoring’ but it’s guessing at best.

Just don’t pay attention to it. Only thing is, sleep tracking is bs, so sleep score is bs and things like training readiness factors sleep tracking into account so that is also … (fill in the blanks)

I'm not sure that the sleep score is bs for many people, even thouogh I agree that sleep phase detection is inaccurate for any device not involving electrodes on your head. The main factors in the sleep score are sleep duration and HR+HRV during sleep (sleep "stress"). Those work ok for many (but not all people). I believe the effect of sleep phases is quite small for the sleep score.
