| Post subject: | MA rating - alternative system |
Ratings – Alternative system Ratings available at: http://www.massiveassaultnetwork.com/ratings.php The main idea behind this rating is that victories can be carried over: if player A wins player B and player B wins player C there is a good chance that player A wins player C. The chance depends on win/loss ratio and the number of games played. It’s also assumed that different maps test different “amount” of player skill. Games on small maps end faster and have lower number of tactic and strategic decisions made by players. Due to this reason a game on New Paradise influences your score more than a battle on Emerald. Relative Score: 12 Emerald 40 NewParadise 25 NobleRust 18 Antarticus 8 Bizzaria 40 Wasserland 30 Anubis 10 Brimstone 15 Crateus It’s also assumed that a player can have a bad setup of allies. So the rating encourages players to know when to retreat from battle and decreases the significance of those matches that were ended in few turns. In general 3 turns are allowed on small maps(20% value), 4 turns on medium (Anubis, Noble Rust) for 30% value and 5 turns on large (Wasserland, New Paradise)(40% value) to decide whether you want to play. The value of a game reaches 100% at turn 5,6,7 respectively. The last but not the least feature: it reduces the significance of old games to represent your current skill, not your average skill. Conclusion: This alternative rating system is much fair in terms of identifying the strongest player of Massive Assault Network than the one experience-based used in game. So the best way to take the first place is to challenge a player from top-20 and win (and do it several times). Comments: turns: it's your only choice whether to surrender or not. If your PL opponent invaded 2 of your disclosed allies on his first turn and your ally distribution is bad you may consider surrender. The idea was taken from Prefferance game (if you have bad random cards you can say "pass", but don't complain about it). The other thing: rewards for longer defensive fights were implemented originally, but now they are off because we don't want to force longer games. The turn count also deal with "multiple challenges" problem. Points awarded: points are recalculated every 12 hours on the basis of games finished. There is a simple iterative process to distribute points of each game between players (player A wins B on Emerald, B wins C on Wasserland, C wins A on Noble Rust...). It's like a affiliate (referential) program. The degree of affiliation of first level between players depends on their relative score in matches between them and the total score of their matches. Other levels of affiliation are calculated when needed. A one global coefficient applies here to determine the percent of points gained through affiliation. The total sum of all scores in table equals the total scores of all games. One more thing: games with MENTORs are ignored. Regards, Wargaming.net Team |

Can't seem to find myself listed on Bizarria, but I have played it two or three times. Is there some minimum score/games played/age of games thing? |

I think you have to win a game to get points (and thus, make it to the leaderboard). So, if all your games were losses on Bizarria, you won't show up. |

I think it's a case of one win, one loss. |

If you have no wins your rating is zero and it goes up with every win and down with every loss. The number of points gained depend on your opponent and one win is hardly enough to make it into top-50. |

So is that a top 150, or are there only 150 players who have won a game on Bizarria? |

There are a total of 231 winners on Brimstone now. The version with pages is available after you've logged into your MAN profile. |

I notice the subject says MA, but it's really MAN since it includes MAN only maps. How is your score affected by the inclusion of maps you can't play? |

Your score is 0 on those maps where you have no wins. Global score takes all games into account with correcting coefficients stated in the first message. It doesn't care whether all the games are Emerald games or equally distributed between all maps. |
