@Dee As part of consulting work (paid and otherwise), I've occasionally had a look at analytics setups and what people were measuring.
Exactly zero of the systems were measuring what people *thought* they were measuring.
This is something I've long been complaining about publicly; your metrics are almost certainly worthless, and will lead you to wrong decisions.
Interview 10 random users and you'll get a much better insight into the state of things than any amount of analytics will give you.
