[phenixbb] Low rmsd values

I am getting quite low rmsd values for my structure. I am finishing the
refinement and I have rmsd of 0.003 Å for bonds and 0.67 for angles, with
R/Rfree of 0.148/0.176. The resolution is 2.0 Å. I am refining with riding
hydrogens and using the automatic weight optimization.
I have also tried to change the weights manually, but the more eye-pleasing
rmsd values always result in worse Rfree.
Is there any reason to worry about the low rmsd values and should I always use
the optimized weights in refinement?
I am using the latest version of Phenix.
