why don't you just familiarize yourself with the map CC values computed
per atom or per residue, for a few different structures at different
resolutions? It might take you a few hours but from that point on you
will have some reference between the map CC values and actual map
appearance. phenix.model_vs_data or phenix.real_space_correlation can
compute all these values for you.
I did it at some point to educate myself and never regretted about the
time I spent doing this -:)
