Running a 1000 key phrase check right now, most results stagnant, but with some up + 1 and some down to - 3 position changes. The biggest changes are all negative so far.
In the first 300, only one new term added.
What I'm also seeing is that if the page title contains the terms, it ranks. It's as if Google is not going very deep into content yet. Most sites (if not all) that rank are CMS style, like WP where you can enter tags and it produces a new title for that tag, for the same page of content. Seems to me like a poor way to qualify a site's quality since it's just open to keyword manipulation again.
Hopefully subsequent iterations will dive deeper and begin to sort out the thin trash & rehash.
