The main reason why Google lost its share in the past few months...

Google gained search share in April. See [online.wsj.com...]

There is a lot going on with Google and we may need to approach the Google SERPs from an entirely different model than the "data set" concept that we've been using in recent times. I'm currently thinking of something more along the lines of waveforms and continuous statistical testing... with near-real-time adjustments and experimentation in a kind of feedback loop. Something like automated algorithm evolution.
