If possible, can you please tell me if you are seeing the Caffeine dataset from 0am to 5am local time and the regular dataset for the rest of the day?
To be honest I'm not quite sure. I would bet the dataset from 0am to 5am is more "caffeinated" then the other one, but both datasets seem to be new somehow, because I never saw this constellation before (at least on the SERPs I watch).
@internetheaven: Great ;-)
