Apple Watch sleep data is more accurate than AutoSleep 😳

But not the same algorithms interpreting the raw data.
Exactly.
Last year Apple didn't show us sleep time data. This year they do. That shows their confidence, and the result shows.
On what planet is that more accurate? All it shows is a teal-colored bar on top of a slightly translucent darker teal-colored bar. No details, no analysis, nothing.
I did see your screenshots, it's that that you didn't really show anything because you conveniently (unknowingly?) didn't scroll down to where Autosleep shows detailed sleep information, such as what time you fell asleep and what time you got out of bed.
It's on the first photo already, showing AutoSleep thought I woke up just before 5 am. Around 20 minutes short.
(and "6:44 Sleep time - top small wheel - confirms it)
AutoSleep lays down all basic informations on the big wheel. You don't have to dig deeper for ones.

As far as I can tell that colored bar atop the wheel (or, as they call it, the clock) is just a rough estimate and gives you a visual approximation. Have you checked what the actual and accurate reported times are when you scroll down? Does it still report your wakeup time as shortly before 5am, as is indicated on the clock, or does the detailed information match what Apple Health reports?
Out of curiosity I went through the last week of sleep reports on both Autosleep and Apple Health, and the information is 100% identical.
Interesting. I wonder why it interpreted your data that way. It's too late now but if you select "Day/Edit" at the bottom you can inspect in detail what sensors were active at what point in time and what Autosleep's interpretation of that specific datapoint was.
Another thing I just remembered is that Autosleep requires calibration before it works properly. Select the day that reports incorrect sleep data (in your case Wednesday) in the Clock menu and tap "Adjust" at the bottom right of the clock. You'll then be taken to a menu where you can fine-tune Autosleep's algorithm to your specific movement patterns, heartrate, etc.

The problem here is not a digital one, it's biological. Both programs track deep sleep(REM) using 15-minute increments.
REM sleep is the most important measure of healthy sleep. During REM sleep, you are paralyzed. This is what the algorithm is tracking. The question is, can you move in and out of REM sleep in less than 15 minute segments and the answer appears to be yes.

Slightly OT, but I have an AW7 and did use Autosleep up until last week. Bought myself an Oura ring and it is 100% almost to the second correct. Also very good with Deep, REM, Light sleep etc. Worlds apart from the Apple/Autosleep algorithms.
Does anyone else use an Oura ring and an AW?
EDIT: Not wanting to derail the thread.
