By default each one of the options shows statistical data from the last 5 days. However, users may freely adjust the time period for which information is shown. The statistical data now available for consultation was compiled beginning on 30 July 2008.
The number of results per page can be adjusted by the user, between a minimum of 5 and a maximum of 100 (except for data on most visited content types where there are less than 20).
