i am not demanding or expecting anything, but i am curious. my guess (and this is mere conjecture) is that streakiness is not a factor in the ranking system. you and the thread creator seem to understand the system completely and can grasp how different elements of the trueskill system affect ranks in different ways, so i am eager to know if either of you have any concrete reasons to suppose that streakiness is a factor.
OK, so there was a discussion about winning and losing streaks affecting sigma/skill. So, at that time I decided to email MS about it and ask. As it turns out, in the Xbox Live TrueSkill system, it DOES NOT take streaks in to account. Now, we know Bungie uses a modified version of TrueSkill so we can't say with 100% certainty one way or another but still this is useful info.
Here is the email response I received:
TrueSkill as used on Xbox Live stores one mu and one sigma value for each game, game mode; as such, it only takes into account the current game but never considers a streak of wins. BTW, we are currently attending the NIPS conference where we present a paper and an analysis on the game of Chess were we do take whole streaks of wins and losses into account!
Best wishes,
