Yahoo MindSet : Sort your SERP's

Yahoo MindSet use a slider bar to sort your result form Researching pages to Shopping pages. After a few dozains of queries, I admit it's working not so bad 50% of the times for the 10 first results. But the best results were found when you set it half way in Shopping or Researching Mode. If you go to the maximum of the two mode, the results will be worst.
