It means you got VERY different results than 2 others who put
their results into the Faq-O-Matic.

You got twice the capacity, half the speed, and a substantial
waste of space between files compared to their results.

1) is it reproducible?
2) are you certain compression was turned off?
3) do the numbers (capacity, speed) seem reasonable?
4) can you explain the difference between your results
   and the previously listed ones?  (tape size, eg longer,
   technology, eg. xyz-2 vs xyz-1, slow, narrow scsi)
