Sleep widget

seems to work, says i had unrefreshing sleep which is how i feel this morning lol

it shows up on the watch widget and as a separate line in garmin connect phone app

Improved how?  Is it possible to determine an accuracy change after one night?  Will you be trying it this evening? 

After 1 night the new widget seems pretty accurate.  I really like the sleep score to summarize the night rather than trying to interpret the raw data.  My score was a 73 and quality Fair which matches how I feel.

don't know, but it did pickup the 2 times i had to get up

I tried it on my 945 last night.  I think I'll need to use it for a while before I can comment on the accuracy.  The data looked just like any other night prior to the update only on a widget. It said I didn't get enough REM sleep, but REM sleep on ANY wrist worn device is a joke and just a random number thrown out based on clinical studies.  To be in REM, you must have rapid eye movement, increased brain activity and slight muscle twitching, otherwise it's just deep sleep. At most, the watch might detect the muscle twitching.  I'm only concerned about awake time and what the light and deep sleep is showing.
