Maybe some of this is a little far fetched but god would it be fun to dig into.

My sentiment exactly! This seems like the sort of thing that would enable people to seriously improve their lives in a lot of different ways, but there are also many more ways to use it that probably wouldn't help much or at all. That's why I'm trying to focus on ease of use--the more people out there experimenting with measuring different things in combination, the sooner everyone gets to benefit from those methods and combinations of measurements that actually do help.
