So today's primary development requirement was to compile the group history into a readily-used form for doing back-history tracking. Unfortunately, Roger's cable seems to be having some difficulties, and local PostgreSQL refuses to load the database dump from the live system. Major PITA.

So, network's back up now, but I'm tired and have to get up early tomorrow, so won't be doing the group-summary calculations before the weekend (which starts now, IMO).
