About online rankings and leaderboard

I'm currently working on some server updates that'll allow players to keep a track of their win/loss when playing online.
I'm also considering of adding a "Gamer Score Value" in addition to the regular score you get. The GSV will be a calculated value that will represent the efficiency of your score, and will be a better starting point for making a Top-10 list for the leaderboards. It will e calculated depending on your score, and time needed to get to that score.
Most of the code is already in my local test server, but I'm waiting up to make that public until I add a few more things to the game client, that I also want in there.
