Hi Emily,
- is it X-ray data set?
- are you deriving average B from a well refined model?
- what are R-factors? Overall and per resolution shell?
Use can use it as a guide, page 25:

The problem with the plot is that there is no error bars shown..
I don't think there exists a tabulated guide of acceptable differences
between mean and Wilson B.
