Hi Claire,

Isn’t the simplest answer just that the EDS server is calculating the 
completeness for a different amount of data (high res limit of 1.92 Å), whereas 
in your Depositor data it was only calculated to a high res limit of 2.1 Å?  
This would probably be the result of you measuring reflections out to 1.92 Å 
during data collection but then manually specifying a 2.1 Å high resolution 
cutoff during refinement.  The refinement program will calculate statistics 
based on your input limit of 2.1 Å, but if the MTZ file actually contains some 
measured data out to 1.92 Å, then the EDS would calculate a different, lower 
completeness if its default setting is simply to use all data present in the 
reflections file.  

Does that explain things, or do you actually have something else in mind as to 
the cause of the discrepancy?
