That's not quite right. If they do the same level each day (except the day they do the full), they will need the media for the full and ALL level

backups since the full (for a complete restore).

In order to restore from the last full and (at most) 1 level, they would need to decrement the level each day after the full (i.e. Full,9,8,7,6,5,4).

No you're incorrect. To quote from the Admin guide, a level backup "backs up files that have changed since the last backup with a lower numbered backup level". So if you always use full and level 5, the level 5 will back up all files that have changed since the full backup, defined as a level 0. You would not need any other level 5 backups taken in the mean time. What you are describing is an incremental backup.
