Yes, it's taken care of automatically by phenix.model_vs_data: it 
automatically recognizes if a PDB file contains residual or total 
B-factors. Twinning is takes care of too. There will be paper about it 
soon. The results of  phenix.model_vs_data run for "all" PDB entries 
forms the database for POLYGON.

If you tell me which structures concern you then I will check.
