Why comp doesn't work

I’ll leave this here:

How Competitive Skill Rating Works (Season 13)

The rating and matchmaking system is confusing, and a good overview does not appear to be available. The official overview (1, 48) is incomplete and does not answer a number of common player questions and concerns. This information below is gathered from sporadic blue posts and developer update videos, and salted with my own experience and experiments, various forum threads, and watching streams. Note that since Blizzard does not give exact algorithms, I do have to fill in some gaps, or leave so…

Might help you understand some of your questions you might have as to how the skill rating seems to work.
