To a Unix fanboi, this seems obvious :-)

I found that not all of the numbers were different. Some of the
differences were very small. Sometimes vectors were given in the
opposite order (there's a note in the AI about that not being a
problem).

The internal checks did all pass, so presumably the differences are
tolerable. But IANAM so I don't know!
