[quote][b]Posted by:[/b] RecklessOWNAG3 Very informative. I was taking a look at the TrueSkill calculators by Microsoft but didn't have a clue what Mu or Sigma was. And was wondering if there was anyway to find out your own Mu or Sigma. Guess not. The calculator(s) are here btw: [url=http://research.microsoft.com/en-us/projects/trueskill/calculators.aspx]TrueSkill Calculators[/url] [url=http://research.microsoft.com/en-us/projects/trueskill/faq.aspx]TrueSkill FAQ[/url] Both from Microsoft.com[/quote]No, there isn't a way to get your own MU and sigma values for each playlist.
