Forgive me for saying this but the object of refinement is to build the most accurate model, not to obtain the lowest Rvalue, which will vary with weights applied to diffraction data versus constraints.
This is all true. Although if one observe increase in Rfree, it is cheap to try a few simple and obvious things to see if one can fix it.
There have been multiple posts about this on crystallographic BBs in the last few months ...
Yes, some of these issues were brougt up in the past in phenixbb (not 100% sure, but feels like this). Pavel.
