Yeah thats kind of the point - to see if you essentially move the selected one up or down after your vote. It just uses the star rating system behind the scenes so you can eventually see the score via the stars if you click on the maps.
I know its a little tiny thing that took me way longer than the seconds it took people to vote, but I had a thought that it might be worthwhile if I can set up a bunch of them for like a single game so over time we have some top 10ish leaderboards for maps, guns, perks, etc. Its led to some good discussion so far and some cool insight in a different format.
