I imagine the flip will be within the next few hours, along with some sort of long-tail influence change. There was also a change sometime mid-day with this.
The original rankings I was seeing around the 25th are no longer. Page-category disappeared again and is replaced by an inner-page. Something to do with synonyms I guess. Huge, huge problem and no idea how to fix it. From bottom of page 1/top of page 2 when the page shows up to page 5+ when they show the inner-page. The page is relevant as it gets great views-per-visit when they get there. No idea why G wouldn't like that and show the other page instead.
