@ Richard
I seriously thought you were joking about the Connect Four but you are absolutely right in what you say about it and other games. A few years ago, I think it was on a New Year's Eve, I saw a mother fucking rock, paper, scissors tournament. These dudes were dead serious about it too, they had nicknames and wore costumes and shit. I forget what the winning purse was but it was in the Gs. Sorry I lol'd you and good luck with it, it's a good idea.

I remember seeing thread after thread in the Bungie forums about exactly what you/we are saying. There were guys on there breaking the system down and explaining the way it works. I think that was before they changed it though. As for what happened to you, I think that the system seen the teams you were playing as "inferior" to your team so you were "suppose" to beat them. I think you only rank up when you are winning or placing high against opponents that are suppose to be better than you, even if only slightly. But 12 games in a row sounds suspect. I could be way off on this too but what I got from my days visiting the Bungie forums was something along these lines. I also have a theory on when you play. I think weekends are a better time to rank up due to their being a larger pool of players. Could just be a coincidence as well but it seems to have been the case for me.
