Questions about "True Skill"

How exactly does it work? For example, if I do good in SWAT, how will the other playlists be effected? And Does it calculate my skill by wins or kills or both?

And when the ranked playlists come out, how much different will it be than True Skill but a number next to my name? I’m sure there are other players that have the same questions.

True skill is seperate for each playlist. If you have not played in a playlist the trueskill is 0

If ranked playlists are added then you will start at zero and your trueskill will be displayed.
