I have been using elipsoidal truncated data all long. And at first i couldn't find a well homologous model (50% homology is the best i can find) so I use Mr Bump and Buccaneer to create a model to phase and autobuild. After a lot of refinement I obtained "good" model with good statistics. Then I used this "good" model to either phase and autobuild again. So this may be due to the model bias?

Is it a problem if the r-work and r-free values are equal? After phasing with phenix, i clicked on the phenix.refine ribbon. Since then for every macrocycle of refinement, r-work and r-free values are always the same. Is this a problem that I need to fix?
