Thank you! At the end it appears that Zanuda is not really a "зануда", translated from Russian as something being depressing, disagreeable or unsatisfactory.

However, at a recent workshop I ran into a case where pointless misled me. This was a case with tNCS where one of the translation components was half a unit cell edge. As a result, the calculated diffraction data would have alternately strong and weak reflections along that axis regardless of whether there was a crystallographic 2(1) axis or an NCS translation of 1/2 parallel to that axis. Pointless assigned a 2(1) axis where there should have been a pure two-fold. On the other hand, Zanuda tried refinement in all the different possibilities and only one refined well.
