Actions per visit

Hi,

Using piwik to audit usage of our Confluence wiki pages. I created a filter on the Recent visits widget: “Page name Is ‘name of page’”.

I see in the recent visits widget for example:
[ul]
[li] 2 unique vistis
[/li][li] 13 page displays
[/li][li] 1188.5 actions per visit
[/li][/ul]
and also e.g. 8 visits and 2777 pages shown.

What does the ‘Actions per visit’ mean? The number seems very high for one visit.
Also the number of pages shown seems very high for only 8 vistis.

Is my filter nog correct/complete?
