Yes, in weewx rain is the total rainfall that occurred in the period concerned; for a loop packet that is the period since the last loop packet that contained a rain field, for an archive record it is the period since the last archive record ie the archive_interval. It is not uncommon for some stations to report a cumulative rain value, most (all?) weewx drivers handle this by caching the last seen rain value and using the difference between that and the current rain value. No matter, sounds like you are on top of it!
