The problem here is in whether you use hardware or software
compression.  The original question seemed to imply hardware
compression, in which case there's just no way to know how
much tape is really being used.  If you need to keep close
track of tape use you want to use software compression.  Then
the above will be true.  If you just want to get the data on
to the tape as quickly as possible, the easiest thing to do
is to underestimate your tape capacity a bit and go with h/w
compression.
