It works backwards from what you describe.  The full backup is the
most recent one, then there are increments going back through history.
So it is easy to delete the oldest ones and keep the last 7 days.  It
is impossible(?) to delete from the middle of the series.

You should just burn the most recent archive to CD.  

If you have enough room, you should burn the full + rdiff-backup-data,
so then you can recover any day in the week.
