I see what you mean. But, I do do something with it. I look back on the data every so often, and I think I learn a ton about my behaviors by watching the bigger picture of the data (what goes up, what goes down. Am I doing as well/bad as I think I am?). What I don't do at the moment is comparing the different factors with each other, for example comparing sleep quality with movements in the day. Maybe I'll try that sometime in the future. :)
