But then surely, adding a prayer to St. Isidore of Seville [0] before every release will be better than just the both of them, so three > both > one.

I've recently interacted with a startup where the amount of resources they spend on trying to get them both, is making them blind to the power of one. It's not a pretty sight when all the numbers are tracked, plotted and planned on, yet nothing seems to work.

You can misuse everything. As you mentioned: "all the numbers are tracked, plotted and planned on, yet nothing seems to work." Sounds like there's a plan but no execution / follow up. That's not a problem with either analytics or user feedback.
