Looking through the PVPUI code and I noticed they had these functions that don't appear ones created in the file.

I would have thought they would have successfully got the information for you when the ConquestFrame was loaded up when the addon was activated. But maybe it is when the frame is shown that the work happens.

Hopefully some of that helps you, if you haven't figured it out yet.
