[phenixbb] Further question on Rwok and Rfree

Dear All, When we run 3 rounds of Phenix refine, both the Rwork and Rfree are satisfactory. However if we run 5 rounds of Phenix refine with the same strategy as the above 3 rounds, in the 4th round Rfree starts to increase until the end of the 5th round. Although by the above 3 rounds of Phenix refine we got satisfactory Rwork and Rfree, can we say the results got by that 3 rounds of Phenix refine are acceptable? Cheers, Dialing
