How does the Governance Report count the visits and values?
Every single request/call/ opening of an element in the hub counts and will be shown in the report. As a small example. You've published a diagram and PDF and got 1000 visits since the published date. Today the users are clicking the diagram 100 times in the Hub, the Report will show you 1100 visits. It doesn't matter how you access the resource/hub, the system counts every single click and put it in the report.
To calculate the result of the date, time range. The system is using the local time variable. As an example for a month, it counts from the 1st of May 0:00:00 until the 31st of May 23:59:59 and give it back in the report.
