The point is that *once you have a 3D representation of the RL*, you can map whatever RS metric you like on that presentation and articulate
its effect on real space. In case of resolution measures this is straight forward; where it becomes interesting is at other atrocities and mutilations of the data, some of which Gerard has already mentioned. Ultimately, once you have classified and ranked the defects of data collection, you can look for them proactively and take corrective measures already in the data collection process. To some degree the automated collection and processing programs do that (e.g. exposure) but there are significant deficiencies that are stated posterior but not addressed in the process (e.g. optimal detector positions, orientations).

Dear Bernhard and Gerard, congratulations for nice results that both you (and Gerard team) have been contributed and published ! Just a nice occasion to remind (and slightly correct Bernhard's message in that article) that the 'efficient resolution' that we suggested (2013) is NOT a single global number but exactly what Bernhard is saying : this number may vary, and sometimes drastically, from one direction to another, and our program gives the minimal - maximal - mean values as well as a histogram of its distribution and a list of major outliers (see some examples in Urzhumtseva et al., 2013, Acta Cryst D69, 1921-1934, and especially in J. Appl.Cryst., 48, 589-597 ). Obviously, full 3D-STARANISO-views of various data quality metrics are much more spectacular !
