Yes, but doing what you've done here gives the entire site, whereas implementing it from the definition allows you to compute the actual values, as I did.

Of course, Google have twoke their algorithm so it's no longer exactly as they originally published, and they're not telling anyone what it actually does. Using the "clean" version is at least transparent.
