Counter History for last 10 recorded day’s Session - Total

I am trying to learn about Statistic reports in Zen Cart. There is one report in the middle of the page in Zen Cart Admin titled “Counter History for last 10 recorded day’s Session – Total”. I could not find information about this report in Zen Cart Ebook. There is two rows for each day. There is a small number followed by a bigger number for each day.

Does any one know what these two numbers represent?
