I was going to say the same thing, until I checked the
7zip web page and found that the -tzip option specifies
a standard zip file, not the 7z format.  Interestingly,
7zip claims to improve on the compression ratio even
for the standard format (e.g. about 7% better on the
Canterbury Corpus file set).
