I am using the "More User Info" option in the dashboard but I see some discrepencies with the report..
When choosing "More User Info" option from the Enterprise Dashboard Overview page, it shows "Top Instances of User Counts".
This page show the Peak User Count for 4 types of users:
Continuous Application Insight Power User - Peak User Count
Service Virtualization Power User - Peak User Count
Application Test Power User - Peak User Count
DevTest Runtime User - Peak User Count
For User where there is detail, the # of Users represents the number of users that were concurrently logged on for that time frame. This count identifies the largest number of simultaneous users for each user type during the specified time period.
So for example, you have # of Users for Service Virtualization Power User of 4, but if you view the Usage Count Details and it shows 6 users. Four out of the 6 users were all logged on during that time at the same time.
