Are the sleep insights real data?

the sleep insights are completely bogus.   I have sleep apnea and insomnia and consult with a sleep physician.   My issue is you could literally wake up every hour on the hour all through the night and garmin will probably tell you you had great sleep and good body battery gain if your heart rate stayed low.  Even though they themselves will record you as being awake most of the time.   So how long you slept is probably alot shorter then what Garmin actually thinks.     They do indeed record you falling asleep and waking up at the right times.    But your actual deep and light sleeps are very inaccurate and it seems their main metric for sleep insights is amount of total sleep calculated.  They don't seem to correctly interpret their own data of continuous sleep and restlessness to determine real sleep.

I use to count the amount of continuous time with low movement to interpret my own quality of sleep,  but on the latest sleep widgets they now removed that data and changed it to "restless moments".   I'd rather see the raw movement data because I doubt they are interpreting that correctly either so now the sleep function of the latest garmin watches have absolutely no use to me.   I'm so disappointed, not only did they not improve their sleep calculations,  now they cheapened the data they give you even more for another gimmick.

I have absolutely no idea what is the average sleep duration for an average person, but please bear in mind, that garmin users are usually much more active physically, than an average person. I am a 46-year old male with no diagnosed sleep disorders, I do long distance trail running, and I get easily 8-10 hours of sleep during high intensity training periods.
