[quote][b]Posted by:[/b] SnyderMan I thank you very much but in the truth bungie is only slightly based off of this and as they said before they will not discuss thier true ranking system with us because it is very hard to understand and if they tried to tell us most of us would still not get it because they use very complicated methods of coding and proccessing over xbox-live.[/quote]There has been a lot of new info discovered since the original post. Yes, Bungie uses a modified TrueSkill system but through examining a ton of games and gamer tags, reading the MS pages, reading posts by various Bungie employees and reading the PowerPoint Bungie published, we have surmised how H3's system works fairly closely. Yes, it's hard to understand but there are some that understand it. The info that has been given in the last 20-30 pages is the most recent and accurate.
