On the ranked matches on Xbox live, how is your score determined? I am fairly sure it is a
"true skill" ranking, but it doesn't seem to be dependant on number won or any other obivious stat.

Short answer:

Basically the system tries to predict if you will win or loss based on the skill level of the players.

An very simple example is:

Predicted to win  and win  = +1
Predicted to lose and win  = +2
Predicted to lose and lose = -1
Predicted to win  and lose = -2

Sometimes you need to win thousand matches to rank up, and sometimes loss just a single one can put you down in the rank.
