How to do you geofilter to get the same server every time for Halo Infinite matchmaking?

[Halo444]

I have set my geofilter raduis on the DumaOS to be pretty small.  But I have still been getting servers outside of it every time.  I have been blocking them as I have got them but I have still not been getting my preferred server.  Am I doing something wrong?

To Geo-Filter the game you have to use Geo-Latency which can on occasion mean you get games outside your radius, to reduce this happening the best thing would be to include a few more servers within your radius so the game has more to choose from

This is my radius.  I have it set to get the Seattle and California servers for Halo infinite but Oklahoma and other servers keep popping up.  I thought this radius would large enough.

Use the simple mode instead of polygon, does that work better then?
