But only if that knowledge leads to something actionable. Otherwise, it may be satisfying, it may be "fun", but I don't see any power to it if it goes nowhere.
A similar axiom that we pretty much lived by in my line of work was "if you don't measure it, you can't improve it". But again, if you get the measurements, but don't have a meaningful response, you won't improve it anyhow.
So if I find I spent $xx.xx on gasoline last month, and that is 10% more than average (per day, accounting for different days/month), what do I do with that knowledge? If I'm thinking about minimizing trips and watching my driving to be fuel efficient, maybe I needed to drive 10% more miles that month, or more stop/go driving, reducing average mpg. So what?
