Does not work at all! Nothing happens!
All except the "last 7 days" time seem to report the overall time. Also takes a really long time to generate (for overall).
Did exactly what I wanted it to do.
Could have more features, takes a little while to do it's thing. A decent stand in while Normalizer site is out of service.
