You should maybe stress more that your OP is purely speculation then. But as this is just your speculation, there are few things I have to criticize.

I saw you saying TrueSkill in in another thread, so which is it? Elo ratings are not synonymous with skill ratings, you known. And considering 343i’s affiliation with Microsoft, it’s far more likely that they are working with TrueSkill as the back bone rather than Elo ratings. And the difference is kind of significant because Elo only works with one variable while TrueSkill works with two.

Oh, not at all. Elo system has a fairly good Wikipedia page and is really not that complicated to explain the basics of, and TrueSkill, although uncomfortably complicated once you go down the rabbit hole, is still simple to explain in principle as long as you don’t go into great detail about team-based matchmaking and rating updates.
Elo I almost explained in my previous post. The system uses differences in players’ skill ratings to compute their win probabilities (expected performance). It then compares the expected performance to the actual performance, and the resulting change in rating is proportional to that difference. If the real performance is more than the expected, the rating goes up, and if it’s less, the rating goes down. The rating change is also proportional to a number called the K-factor, by which the performance difference is multiplied to arrive at the final change in rating.
The K-factor is not that significant when we discuss Elo ratings, but matters more when we discuss TrueSkill. The short story is that TrueSkill is “like Elo” (notice the quotation marks), but with a variable K-factor which also changes based on how much the player’s performance corresponds to their expected performance. The reality is of course much more complicated. The update formulas of TrueSkill are much more complicated than those of Elo, and not really worth discussing because of that. But the gist of it is that aside from just keeping track of player skill, TrueSkill also keeps track of how reliable the estimate is, which makes it much more flexible.

It’s unlikely that K/D has any effect on ratings. 343i were very clear that winning is the only way to affect your rating. The last season’s CSR affecting placement matches I could get behind though. I’ve said before that throwing away a completely good skill estimate is just silly. This is also where the advantage of TrueSkill comes in: blowing up the rating uncertainty to some big value at the start of every season while retaining the old skill estimate is much more sensible. It’s in essence as if your rating had been wiped clean, but it still tries to match you with players of appropriate skill level from the get go.
