How do Blog stats work?

Hi, I’m with https://www.sfbulldog.com/alexandra

I can’t figure out how blogstats are assembled. It seems like the “top posts” category should list every view and which post was viewed, and that the “referrals” and “search engine terms” should just be redundant explication of how the viewer got to each post. Sometimes I can match up the search terms with the posts that were viewed. Sometimes the referrals, search terms, and post views all add up to “total views” displayed. Often when 1 total view is displayed, there will be “none today” listed in any category. And quite often the “total views” exceed any way to account for them.

Can anyone shed light? Thanks.
