But why would more level 0's give you more _real_ "value" if amrecover
takes care of which tape to go to for the files that you request?

If I were to need to restore the entire file system, then certainly
restoring from one single level 0 tape would be more convenient than
to restore from one level 0 plus several level 1 and level 2
tapes. But in the case of restoring only several files, which is
generally the case, as long as all changed files are backed
up somewhere, the only difference is to locate the right tape for
the files needed. Right?
