Display more then 100 total number of visits


I have asked this question before but have not gotten a working answer yet, so this is an attempt to give the question some attention again.

We are using Piwik to track visitors. Using the API we show our user managers how often their users have used our knowledge base. They have requested us to show the total amount of visits by user. Piwik shows a maximum of 100 visits for a user. A bunch of users exceed this amount by a lot, and there is no way to differantiate them anymore in visits. This is one of our requirements.

Is there any way to remove the cap 100 and display their actual amount of visits?
I have tried the: filter_limit=-1, but this does not seem to work.

We are using the following query.
