It hasn't been 5 days in several releases. That's a leftover from before security-in-soyuz when we needed 3 days to copy the archive into the separate DAK instance used for -security.
1.5 days from the start of release day is nominally 12 hours for discovery and correction of some last minute really, really serious problem and 24 hours for mirror sync.
Since it takes having a package to publish to trigger a publisher run, it's useful to have some unseeded packages in queue in case last minute seed changes are needed.
