Really surprised that Autosleep performed so poorly. I've been using it for over a year and I'm pretty satisfied, and chose it because it was the only apple watch sleep app I could find that didn't require a monthly subscription. Admittedly I don't look at the 'score' so perhaps that's it, I just look at the overall 'quality sleep' hours and have found that tracks pretty well with how off-my-game I am that day.
