[phenixbb] B-factors vs resolution

I am refining a 1.3 A structure the maps look great and I notice the 
main chain B factors are all around 7~12.
I have refined the same enzyme at resolution 2.2 A and the B factors 
here were around 25~30.
The question that comes to mind is:
Usually one will describe ordered parts of a protein vs disordered 
parts based on B factors. Is the higher resolution protein more ordered 
and that may have contributed to its stronger diffraction?
Or are the B factors values artifacts of refinement?
