[quote][b]Posted by:[/b] l KxS Lyle l Ok does negative exp boosting acutally make your Mu higher so you actually rank up faster and dont' de-rank when you lose?[/quote]Quitting a bunch of games will make your sigma higher and lower your skill level (MU) in the playlist you quit in ONLY. As soon as you start winning your MU will go up and your sigma will go down. Neg EXP boosting is not the "trick" everyone thinks it is. Quitting a bunch of social games to boost your friend in Team Doubles will not work. It's sigma and NOT EXP, that is at work here. You have a separate MU and sigma for each playlist. It is your sigma, MU and a couple other variables that make up your displayed skill level for each list.
