I've heard many admins refer to such things without any references.
I've never seen documentation of it before.  That doesn't mean that it
doesn't exist.

Very close to that concept was an older model drive (SDLT or something
maybe) where it would disable compression if the tape wasn't keeping
up.  But even that drive wouldn't *skip* tape to keep up.

%used is just a networker aid for you to guess at tape capacity.  I
don't think it represents anything more than "written" divided by
"capacity" and capped at 100%.  So yes, it should.  (I think it would be
easier to check "written" directly, though).
