No, except 3 curators, I do not see the other curators curating more unique authors as you can see one out of five has its "unique author ratio" much below 0.4, means they are curating more number of repetitive authors. ideally it should always be above 0.4 or 0.5. A number above 0.6 or 0.7 is really a good indicator and we have only one curator in that zone.
