I use a custom variable to store the username of who is visiting my site.
So I access the custom variable report to list all the values of a custom variable, and have a look at the whole list of users.
I would expect a list of 30 users, while the list includes only 5.
This is not any filter in place (the timerange too is set on a long period that does not limit the list of users).
Is there anything I should consider that is faking the list of users/the list of values of the custom variables?
Maybe very short sessions are not considered in the list?
For example, is this post from 2011 still valid?
