Is anyone's apple watch sleep tracking accurate? Mine is hilariously inaccurate

Thanks KiltedTim. I waited a few days to see if there will be any more replies. But based on all the info so far, the conclusion seems to be

1. To get the sleep tracker to log hours of sleep to any basic degree of accuracy, then you can't think of the sleep tracker as an automated digital tool but rather treat it like a manual pencil and paper where you must 'write' (click something and set something up) just before you go to bed. This approach seems to be what KiltedTim suggests. I know that if you try to automate and use Apple's features like sleep focus, then it will not work accurately (which kind of defeats the purpose of a digital 'smart' tool)
2. Inconclusive on the accuracy of the sleep quality tracking (like apnea, REM sleep, etc.) KiltedTim seems to feel it is pretty accurate. In my personal experience, it is hard to see how a watch that believes I am 'asleep' when I am physically moving around the house to be able to measure something that requires even more finesse accurately

So overall, for me, the Apple sleep feature is a complete bust. I appreciate there are users out there like KiltedTim for whom the watch works, in which case great for you. But sadly, for me, it is clear the money I spent on the 'sleep feature' is a clear waste
