According to Gears community manager SixOkay, the Gears 2 ranking system strictly uses Microsoft's TrueSkill which is was created using chess' ELO rating system. This means that ranks aren't calculated strictly by points or kills, instead a rank is determined by your wins and losses AND whether or not you were favored to win the match. Also, the five different icons used to express your rank (viewable above) are used as a general range of ranks attainable, so small fluctuations in your win / loss ration won't instantly change your icon.
