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).

I've worked on a lot of NetWorker sites, and almost all of them do a
weekly full with incrementals or level backups the other days. In
general if they do level backups they will do the same level each day
(e.g. L5) so that they can always recover from one full and one level
backup. Depending on the company some choose not to backup at weekends
if they are not 24x7 operations. Some choose to do their full backups
during the extended weekend window and some choose to spread the full
backups through the week.
I've never worked anywhere where the fulls are less frequent than
weekly. It amazes me to hear of people doing their fulls only monthly or
quarterly. These people must need to be paranoid about re-running any
failures ASAP.
