[quote][b]Posted by:[/b] SwiTcH 14 Quoted from the first post: "Higher Sigma simply means your level is more fluid. Sigma is good to have high when you are still reaching your appropriate skill level, but good to have low once you've reached it and are working on improving." So it's good to have a high sigma when trying to reach your desired level faster. When you do reach it, how do you lower your sigma so it doesn't decrease on one loss, since having a high sigma can increase and decrease your level dramatically? Another question: So your Mu and Sigma is based on your win/lose ratio? So out of like 100 games, your win/lose ratio is like 70/30, your Sigma and Mu will increase?[/quote] Sigma drops significantly over the ifrst 50-100 games of a playlist...drops more if you lose than if you win. Your MU is based on your win/loss, whereas as Sigma is known to drop after every game, even if you win. You gain and lose MU based on your performance against other players and their own MU's and Sigmas.
