popular posts week

Just trying it, and it seems a great plugin; however, you could not have made more user hostile! How do I retrieve weekly popular posts. I see the fundtion strtotime equals today, but nothing for the week. Can I use e.g. “strtotime equals week”? You have put so much effort in this plugin, it’s a shame that instructions are so difficult.
