>Why do people optimize every KPI?

Because if it's not worth optimizing around, how key can it be?

You can do a lot of things with a number that are not optimizing.

For example, you can satisfy it, you can alert on behavior, or you can use it as a control (but ok, maybe this one makes a two number KPI instead of two KPIs).
