Sleep score is ridiculous

I have just gotten my first 100 sleep score. I slept 8.5 hours. Somehow I still feel crappy and exhausted today, plus I know that I had interrupted sleep because I was woken up by one of my kids.

Perhaps there is something else going on with me, but I know myself and I’m sure I just had a bad night. I seem to always get 90+ unless I have a short night, this feature seems totally pointless.
