Podpress statistics definitions

I’m using podpress and it’s working perfectly.

I’m having trouble understanding the statistics definitions and the FAQ and wiki are all 404s at the plug in site (http://www.mightyseek.com/podpress).

Can anyone shed some light on the distinctions between Feed, Web, and Play? I’m assuming that Feed refers to downloads from our rss feed. But which are streamed from our site? Which are itunes? Is there a distinction between outright downloads and streaming online?

Thanks in advance.
