I calculated/validated several PDB structures in Phenix.Validation (GUI)

The R/R-free (overall) is

0.1271/0.1348

Further down I looked at the R/R-free for the highest resolution shell.

Its 0.2538/0.2446

I am curious why the R-free for the highest resolution shell seems to be LOWER than R (work).

Am I reading the information wrong? 

PDB: 3QL9

Thank you,

George
