Thanks @yanokwa for the comparisons!

Thanks @Falco, would you please explain further:

  1. If the correct views are from September, does that mean all the previous counts are incorrect?
  1. So if I understand that correctly, the page views from September are based on the above definition. May I ask what the previous values represented? Is there a way to get the accurate values back?

Thank you!
