Thanks to the significant performance improvements made to updateMenteeData (T290609#7429319), we can now run the updates more frequently than daily.
I think updating every three hours is now possible from the technical PoV (potentially even hourly, but I want to keep some breathing room in case it slows down for some reason).
What would be the ideal update frequency from the product PoV? @Trizek-WMF @MMiller_WMF @RHo Maybe you have some opinions on this topic?
