Instead of repeatedly retrieving the same information, it is cached locally, and that cache is what iPhone Tracker is tapping into.

I cant see primary on my db copy, and my wifi location also contains 33000 MAC addresses.
Indecently, couldn't get the py script up and running on win7, but if you sort by date modified, the size is around 5 meg and you can open the db directly in an sqlite viewer
