Think of completeness with an analogy to turkey.
Say you happen to find a one-legged turkey

Dear Matthias,
Of course,
Thank you all, for your replies! Some of you suggested that there
could be reflections at the corners of the detector, which are 'cutted
by the edges'. This also came to my mind, but the data was collected
until 1.7A at the edges.
I will take the advice to refine against the low and the
Dear Matthias,
Of course, high completeness is better than low completeness.
But as long as your low resolution is pretty much complete, there is no such
thing as "too low completeness" at high resolution. Each reflection adds
information to the map, and serves as a restraint in refinement.

Dear Matthias,
do you have an idea of what triggered this low completeness at high
resolution?
Is it that the crystal still diffracts in one direction of space but
stops in another, resulting in low spherical completeness? If so, then
you can use all of your good data, and I would probably go
Hello, it should be alright especially if you have NCS. Diffraction anisotropy also springs to mind. Best wishes, Jon.C.On 25 Nov 2019 13:11, Matthias Oebbeke wrote:Dear ccp4 Bulletin Board,

The data are > 90% complete at low resolution, where the completeness is more
important, so this is probably fine - you would probably benefit from better
detector placement in the future as the data are good to the edge.
Was the detector offset or just too far away? 120° for an oP lattice
