By the way -- why did you put the option "w" into "-xwzf"? Previous suggestions stated "-xvvzf" (though admittedly the repetition in "vv" is redundant: you can just as well use "-xvzf"); maybe you misread "vv" as "w"?
I copied "tar -xvvzf" from the examples on the manual page. Maybe the double v means, "be even more verbose"?

Hmmm ... I don't have any man page for tar ('man tar') which gives examples of use -- on SuSE, Red Hat, or Debian. Maybe it's an Ubuntu (or other) re-write. In any case, the way command options usually work, a repetition would do nothing extra. Options are read in one by one. When a specific option is encountered, a flag is set in the running code for the command. The first 'v' would set the "verbose" flag. The second 'v' would simply set it again.
Erm, I have a man page for tar in Debian... Maybe you haven't got man installed :p
I strongly suspect a typo in that version of the man page that you are looking at!
It's the same "typo" in the Debian man page.
I doubt that it's a typo.
With verbosity, many many things simply change the output level, so NORMAL -> EXTRA -> QUITE A LOT -> OH MY GODS IT'S TELLING ME WHAT EVERY LINE OF CODE IS DOING
There are several things that take the same option more than once.
For example, run: aptitude moo aptitude -v moo aptitude -vv moo aptitude -vvv moo
Now tell me that the number of times an argument is repeated doesn't change anything. Go on. Really.
