What exactly is Blogpulse counting?

I am a casual user of Blogpulse for trends graphs and while preparing for a presentation, I suddenly wondered what Blogpulse was actually measuring on its "Trend Search" charting tool.

For example, see that dummy graph I created (I was hungry). The X axis is time, and I guess the unit is a day. But what is the Y axis?

It says "Percent of all Blogs". What does that mean? Does Blogpulse counts the number of blogs mentioning my keywords or the number of occurence of these keywords across all blogs for a particular day?

I looked on the site and on the FAQs but no mention of the methodology.

I talked to a few people I know who use Blogpulse and no one knew.

BlogPulse Trend Search graphs the percentage of blog posts mentioning your keywords. That is, for each day, it first counts up the number of unique posts matching your keywords. The Y axis then shows the #posts mentioning your keywords / total # posts for the day (as a percentage).

OK. I get it now. Thanks a lot for your quick reply. Why don't Blogpulse explains that on the FAQs?
