Single Page Visits calculation Hello,About the "Single Page Visits" calculation, the doc says:This metric counts the number of visits where the 'Page' dimension item contained (1)only a single unique value for the entire visit. (2)If a visitor reloads the page or fires link tracking calls, it still counts as a single page visit. As soon as the Page dimension changes to a second unique value, the visit no longer qualifies as a single page visit. In fact, the above description seems very clear, however, I still have a few questions:1. How to define "a single unique value" in (1)?My assumption is something like "Select DISTINCT(PageName) From XX". Is it correct? 2.
