Yes, if the data going to tape is not also software compressed, then the
amount of data written to the tape is indeed an accurate indication of the
effectiveness of hardware compression on that tape.
Save sets that are software compressed show a size much less that the real
amount of data within, so the amount of data on a tape wholly containing
software compressed data should be very close to 35GB.
