I had just bought my pulse hr and using it to track my sleep. However, every night it only records from 11pm upto maybe up to 3-4am.
I sleep at 11pm~ish and sometimes I get interrupted and unintentionally wake up around 3~4am. I go back to sleep and wake up at 8am~9am but the tracker only seems to track upto the 3~4am and i always have to manually edit my wake up.

Hello,
While we await the highly anticipated enhancements to our sleep tracking system which was the winner of our poll; we will be happy to share a quick piece about how the watch tracks sleep stages.
The sleep stages (e.g. light and deep) are measured based on wrist movements.

martin.chrimes - this is an excerpt from the support case when I had the same issue...
"It can take 3 hours of little movement while wearing the Pulse HR before sleep is detected. Even though it can take 3 hours of little movement to detect sleep, once sleep is detected, the sleep tracking is retroactive. This means that if you go to sleep at 20:00, sleep isn't detected until 23:00. Once sleep is detected, however, the Pulse HR will show that the first stages of sleep began at about 20:00 to ensure that you are not missing any data."
I think this means that if you sleep at 12am and the tracker detects little to no movement at 3am, then that is your first 3 hours of sleep. It will then track the next 3 hours (from 3am to 6am). So on and so forth, every 3 hours.
So if you wake up at 5:30am and synch the tracker, the last logged sleep you will see on the app is at 3am. If you synch again after 6am, then what the support person say is it retroactively update the sleep so you get credit for the 3am to 5:30 am sleep. That means you won't see any sleep on the app from 3am to 6am or before the 3 hour detection period. You will only see the sleep, only after the 3 hour detection period is completed. So after 6am~, you should see the full sleep from 12am to 5:30am.
