Hello, I think you are at a mid-refinement stage (R-free mid-thirties and map clearly still needing a lot more fitting work to be done on it) so I would not worry too much about the geometry stats at this point! I should pick someone's brains locally on model-building and get the fit to the map as good as possible.
