Times up!
The 3rd case I had in mind was the presence of anisotropy of the anomalous
scattering in the presence of a polarised beam. John Helli
guess it would also apply to Latin) language.

The traditional benefit was in reducing absorbtion errors. This obviously
depends on crystal path, and seeing it is hard to model well, one way to
mitigate the errors was to average equivalents collected at different
settings. The error was still there, but assuming random distribution about

Can anyone suggest other sources of error which would be mitigated
by having different paths through the crystal. I don't think
radiation damage (mentioned by several people) is one.

Suggestion : any source of error which does not obey the crystal symmetries
will benefit from
