and there were a few others. Point being that all the changes were made between June 23 and July 1. All gains were within a week or so. The traffic gains themselves were between 60-80%. Nothing to sneeze at.
Unless Panda run after July 1st I don't know. As others pointed it out Google might just see new content in a new domain with no Panda score so it ranks then pre-panda.
