I like your chaos theory comment sasquatch!
when you think about it, it must be a nightmare for Google to try and predict the effects of even minor algo changes. All they can realistically deal with is summary data given the time constraints, so unanticipated shifts that are quite significant may go unnoticed. I assume they also track the effect on major players as they don't want the trouble that would come from delisting a fortune 500 company, but that leaves the rest of us vulnerable.
