In the very low resolution world of SAXS, the whole idea of resolution is 
problematic. One can quote the minimum d-spacing (maximum angle) measured, but 
it is not a useful number to report.  People are much more concerned about the 
quality of the data at maximum d-spacing (lowest angle). Perhaps very 
low-resolution crystallography is starting to enter this regime as well in 
which resolution concerns are turned upside down. 

Granted, SAXS is a heavily averaged experiment which can densely sample q 
space,  but which does not even attempt to produce density. 
But the point I think that is appreciated in the SAXS community, is that the 
connection between extent of data in reciprocal space and model features is not 
simple.
