You and Gene seem to have settled on 7,5,1, and 15 or 16 for tapecycle.

Given that, for offsite I'd suggest you consider your tapes as groups
of 5, i.e. 3 groups.  One group will be in use, one group offsite,
and the final group will be either the next group to be in use or
the group that was most recently in use.  The former ensures you
are ready to switch groups over the weekend, the latter keeps some
more recent backups on-site for recovery.
