Subject: ELO rating system

Do you really care? you can't automatically see my signature anyway.

seeing all of the ratings system topics, I went in search for a topic that listed point for point why the halo 2 ranking system failed. I couldn't find it but instead stumbled upon the ELO system

Though those of you that know of the ELO system know that it's a chess rating system to shows your skill based on your wins and loses relative to everyone elses.

as I explain this I'll start with the formula for the ELO rating system.
400 (W-L)
-------------- + Rc = Rp
N

where:

Rp = the player's provisional or performance rating
Rc = the average rating of the player's opponents
W = the number of wins
L = the number of losses
N = the total number of games played (N <= 20 for a provisional rating)

A draw counts as half a win and half a loss.

now why this doesn't work perfectly for halo is that in halo we can play either FFA or Team. so how I suggest this be applied to halo is that your Rc is changed to the average rating of your player's opponents (as a player in FFA or as team avg in Team)

now here is the other issue we'd run into because ratings would be based on team avg's. is that if you and your friends all played your first 20 games together you'd all share the same rating with no chance of individualism within your team.

how to fix this? well in chess you win or lose but in halo you kill, die, assist, get killing sprees
400 (.85[W+K-L]+.1[P-N]+.05[M])
-------------------------------------------- + Rc = Rp
(.85[G+D]+.1A)

where:

Rp = the player's provisional or performance rating
Rc = the average rating of the player's opponents
W = the number of wins
L = the number of losses
K = the number of kills
D = the number of deaths
P = the number of assists (when you win)
N = the number of assists (when you lose)
A = the total number of assists
G = the total number of games played (G <= 20 for a provisional rating)

A tie counts as half a win and half a loss.

tooo complex.... ME NO COMPREHEND DAT THINGY

Your true skill should for one, be hidden (to everyone but yourself).

Second off, it should be determined by:

-Your average K/D per game, and overall.
-Your accuracy (All the rounds that hit an enemy/all the rounds you have shot)
I know this is possible because CoD4 can tell you your accuracy.


Anything else, winning or losing a game, etc. has too many variables such as interference with lag, other players etc.

BTW Elites rule!

And I am probably just trolling you right now....especially if it is a controversial thread

personally, i like it, halos ranking system sucks

Do you really care? you can't automatically see my signature anyway.

you skill is based off of your average opponents skill + the quantity of 400 multiplied by 85% of your wins plus your kills minus your loses plus 10% of your winning assists minus your losing assists plus 5% of your medals (killing sprees (+5,+10,ect) only) divided by 85% of your total games minus your deaths plus 10% of your total assists

I know it's still complicated but maybe reading will make it less confusing for some.

To start off, Go / Weiqi / Baduk is far superior to Chess. If you understood my random Plug... we should play some time.

Second, what is "M"?

honestly winning and losing as a team with an effective skill ratings system that matches you with equals (instead of the crappiness that is the h3 system) would still work great regardless of lag or other variables.

lastly, yes accuracy is measure (it wasn't in postgame for h3, but was for h2) but it's not a true measure of your skill. it's a measurement of your effectiveness with the weapons interface of the game.

sorry M is equal to your killspree medals (this is a way to reward high skilled players that can get many kills without dying and to lessen the effect of unlucky streaks where you get spawnkilled, but it's weighted at 5% so it doesn't effect your score too incledibly

In the second formula, what does M stand for and where in there is N?

Also the top adds up to 100% weighting but the bottom only adds up to 95%. That might be a problem.

Oh, and how does this work for capture the flag? Should I rank up more than my team mates because I'm on defense and I have the luxury of not-risking-my-life-to-storm-a-stronghold-and-smuggle-out-the -enemy flag?

In addition, high spree medals speak more about the abillities of your opponents than your own. I don't think they should be used at all in ranking.

sry bout the N part i just didnt see it. thx for showing me.
Now another question. In ur formula should there be a place where if ur teammates start quiting it shouldnt effect ur skill? Cuz that is a HUGE problem in halo and bungie doesnt do anything about it except take away a tiny little xp point. While u could be on a 20 game streak tring to get 50 and u lose cuz u team left and drop down to a 48.

Wow sry for the ranting it just pissed me off to see that happen to a friend.

Agree. That's why they took the leader boards off in H2. It got too insane and skewed. People cheated, boosted, etc. It encouraged bad playing. Just look at Haloboards where you have people start accounts just to get kills with a plasma pistol or something stupid. Leader boards draw the scum to the surface.

DISAGREE! K/D doesn't necessarily mean anything. You'll have people camping just so they get their k/d up. Once that's up, it's easy to go win some games. Also, accuracy is absurd. Do you know how many bullets the army wastes on suppressing fire? You might not do it as much in Halo, but you use different weapons that have different accuracies. Why should you have to worry about not shooting an AR unless someone is right on top of you? And why should I have to worry about my rank by firing BR bursts past a corner to deter people from poking their heads out?

Agree. Other things like assists or damage done could be factored. That way your loser friend who makes you protect him while he snipes in the back doesn't get all the glory because he's got an amazing k/d ratio at his team's expense.

Great point obviously there are plenty of factors to consider with capture the flag. this is more of a slayer-based equation if I were to do a objective-based on it would consider kill and deaths little to none because i don't think you should be rewarded in objective for camping the objective and racking up kills. i hate having team mates in objective that just play to rack up kills.

I do realise the 100/95 delema, but if it was 50wins - 40loses/93 games, it doesn't make sense when you've only played 90 games.

-I was here

hablas ingles please?

  • 10.13.2009 5:47 PM PDT

Wasn't Halo 2's ranking system similar to ELO?

  • 10.13.2009 5:49 PM PDT

Do you really care? you can't automatically see my signature anyway.

yes i believe it was however i think it was more based on Wins and Loses than it was like my system.

I like your ideas and think they are a good mix of win/loss and other components. I already messaged you with other ideas I had as well. GOod luck!
