Its been a while since I personally refined many structures. In the past, I used as a default, 5% of my unique reflections for the Free R test set. I have a high resolution structure with 150,000 unique reflections and noticed that Phenix defaults are 5% or 2000 reflections which ever is smaller. What is the current consensus on an adequate number of unique reflections to use for cross-validation?
P.S. I really, really love Phenix.
