Maps get worse.... Could it be when you use all resolution range you get 59% of missing reflections in highest resolution shell filled in with DFc for the purpose of map calculation? > Also, taking geometric restraints off during refinement the Rfactors > improve marginally, am I justified in doing this at this resolution? > It's unlikely you can refine without restraints at this resolution. Perhaps, without restraints the model still ok overall, but I would bet there are places that get badly distorted, so have a closer look at your model quality locally (alternative conformations, mobile loops, etc).
