New Usage Metrics - incorrect page views

Hi, 

in the new usage metrics when you look at the view count per page, it seems that only very few views are counted for compared to total views by report. It seems that in the data model sectionids won't connect correctly. Most of the report page views are for sectionids that don't exist in Report Pages table. Does it have something to do with republishing of the report? It seems that sectionid changes with the republish.

Thanks for your help!
