Map creation is a creative process, and in this process, your inner voice is the main advisor. It would seem quite unusual if a renowned artist asked what he should draw. If it comes to the point where you're asking an external audience "what should I do?", it means there's a crisis. Mathematical statistics won't provide a recipe for how to best overcome it. If that's the case, you can take a break from mapmaking. Distract yourself, read, listen to yourself. There will definitely come a time when "Thoughts in my head stir with courage,/And light rhymes rush to meet them,/And fingers reach for the pen, the pen for the paper." At that time, the question being asked now will be resolved without external advice.
