Do you have a simple AB testing system in place to test hypotheses like this? If you're the only sherif in town running experiments, it doesn't take much work to build a simple one, probably around ~100 LOC ("do things that don't scale").
Edit: to expand a bit lest that seem snarky - what I mean is that maintaining the current system takes so much energy that there's precious little capacity left over for creative exploration. This is a problem.
