I have read as much of this post as I could so I do sincerely apologize if this question was asked before. What happens to Mu and Sigma if you quit out/get lagged out of a ranked TS match? Does it even count as a loss? Or is the punishment for quitting strictly limited to losing EXP which at this point I can care less about... Out of the last 50 ranked TS matches I finished completely through without quitting or getting lagged out I won 32 of them, not in a row. In that time I went from a 46 to a 48. So the theory on ranking up slows down as you get higher is supported. At least in my case anyway. Excellent post and many props for the research you guys did on this! If you need a research assistant for in-game data collection, I can help!
