--For most of today, I was ranking lower on lots of my usual phrases. This evening, I suddenly ranked higher on them. This sort of pattern keeps repeating, sometimes in reverse.
--And within that pattern, there are two fairly distinct SETS of keyphrases. One day, it's all my usual standbys that are fluctuating in position, but the next day it's a bunch of other phrases I've never ranked that well for. Sometimes the keyword set will shift during the day.
--Despite all these shifts, I'm getting a set amount of traffic from Google each day, and it never varies by more than about 30 searches.

Zombies are an intensive "scanning" method- using a weighted statistical traffic profile to sling mud at a site and see what sticks. It is used for LOW VOLUME sites... or sections of sites where that site has been differentially profiled by niche. Read that sentence again, it's important.

I have to believe that some sort of throttling is occurring using how many times a url can appear in the serp.
It actually began late June 5, early June 6 and something that happened, at least to me, is that my peak traffic days have shifted, again.
Eons ago: Thurs to Sunday were the weekly peak traffic days.
3-4 years ago: Sat to Monday became the most trafficked days.
Last year: Sun to Tuesday was the peak.
As of June 5/6: Monday to Wednesday is the new peak, from Google.
Now, I know the entire internet didn't shift how often they use the internet on June 5/6, or likely any other of the times above, so something Panda can do is place your site on a different traffic "schedule". (unless Panda isn't the only "change" Google just made)
We've been thinking of rankings as static, you get x% of the searches for your keyword based on your rank, but that's NOT how the internet works anymore. The rankings are in flux depending on site type (informational vs transactional vs locational) and day of week, keep that in mind with any report you make here... please.
