This is what happens when you let "the data" drive design. The data becomes an abstraction between your users and your goals, leading to a paint by numbers exercise where the only thing that matters is getting some arbitrary metric to go up. The results are quite predictable: numbers that go up, and UX that goes way, way down. Eventually this falls over because your model ends up in local maxima.
