How does the data breakdown?

I recently installed the GA plugin and am very happy with it, but made a mistake during the initial setup. While the UA code is entered correctly for all the sub sites, I also entered the parent site's UA code in Setting->Google Analytics instead of via the super admin menu. The super admin menu has been blank since initiating the plugin...

So, can someone tell me what the data is that I am seeing on the parent blog? Is it for that single parent site or the entire network? And, assuming it is for just the parent site, can I track the parent site and the entire network separately by entering a different profile ID?

Lastly, is this detailed somewhere and I just missed it? Apologies if that's the case.

As always, you guys are a big help. Thanks much for your work, advice and feedback.
