A single metric is just one very thin dimension from the temporal development of a complex process involving many factors. You need to watch a multitude of metrics to devise an explanative theory, and even then, that theory can be rendered flawed when new and unexpected factors come at play.

I think the point is the theory doesn’t come from the data (it can’t). It comes from the process of creative conjecture in a person’s mind.
