Auto-exist challenge

Hello 
With the the help of the community I could create a sport result ranked table. 
In one table the ranking can be filtered on
- month
- week
- day
and based on date further filtered on gender and nation. Everything works as expected. The ranking is based on userId (unique) and TotalCalculatedPower.

Problem
A visitor wants to search for a participant with name and the ranking shouldn't change in this case. The auto-exist Dax feature is the reason I assume.
How can I calculate a correct ranking which includes the userId, but ignoes it on UserName filtering ?
