Global ranking system SUCKS

[PopSniper]

I am VERY upset with the current global ranking system and I think it is BROKEN. Over the past few weeks I've noticed an alarming change in how my rank changes from game to game. I lost a recent game on Gap because the two mid players left the game about 10 minutres after it started. Since the game was lost, I elected to cntrl K. My rank went down by 10!!! WTF. I proceeded to win 4 games in a row after that and my largest rank up was a 3. Then I lost another game and my rank dropped by 8!! I've noticed that when I win my rank goes up a small amout but if I'm on the losing team it never goes down by less than 7! I do not understand why this happens. I usually play air and don't get the opportunity to kill many commanders but I contribute a lot by killing off gunships and bombers that could have killed my teammates. PLEASE FIX THIS and make it fair.

The amount of points you lose/gain from games depends on the game quality. If you lose a game that is "stacked in your favor" you will lose more points than you would gain in case of a victory. Also killing enemy ACUs will not affect your rating. The only thing that counts is wether your team has won or lost the game.

While I think some of this rating rating gain issue you are having could be due to team stacking. I think I have noticed a general increase in rating drop per games. I have had 90% games where I lost and lost like 6-9 rating (no jokes intended on that number.) then I would win matches on a similiar amount and only gain like 3-4 rating per.

One thing I have been particularly curious about is some of the coding that was added on august 8th. One particular one...
"7. Add new GPGNet command for enforcing ratings."

I tried to ask around about what exactly that new "GPGNet command" did exactly with the rating but I never really got an answer to it. Although I did note that rating drops seems to have been larger ever since unless it is merely a coincidence. If someone can say here what that new command actually does that would be appreciated.

Regardless the rating system in the current state of things does seem to be overall inflated and could use some love. And maybe another rating wipe and reset like when the rating system changed the first time a few years ago. Most people probably would not agree with a rating reset, but it happened once before and it can happen again if need-be. Besides, I think that would help some of the present inflation if that reset came with a significant change to the rating mechanics. I imagine it would be tricky. But hey, open-source client. As long as people with the time and know-how are willing. We can get anything done.

The rating system works fine except a few things. Normally the overall rating in a game with all players should be something arround 0 at least not a high number means: Sum of winner team rating - sum of loser team rating should be more or less arround 0. Not necessary that this will be 0 but it should not be a big difference. I played a 64 Acu game ffa. Such games are rated. I expect since there will be 1 winner with 7 losers for example and the chance to win is very low 1/8. The losers should lose normal rating 5-6 and the winnder gains e.g. 7x6 rating. What happens atm i lost 50 rating in this game and i expect that all other players who lost also lost arround 30-50 rating. No idea what the winnder got but he didnt get 7x 40 rating for sure. Something is broken there. If somebody wants to cheat the system and plays lots of 64 acu games he will be underrated soon.

I think it's counting it as 7 defeats for you, and 1 win for the winner.

The trueskill in principle works OK, I'd say.

But at the moment it seems that half of the game results are not processed due to some bug. I don't see how else after winning 3 out of 4 balanced team games I could drop in rating.

At some moment I suddenly had a drop of 40. I think that that is due to a 2v6 that counted as rated. That game was heavily stacked in favour of the 2, but the system probably sees it as the other way around. Games with an unequal number of players per team used to be unrated and should remain unrated in my opinion.

I would like to see which results the system calculates with, but what the Replay vault shows as win/loss has been corrupted since the server changes a year or so ago.

The randomness of the result processing does even things out, so the rating that you have should still be roughly correct. But it is not rewarding if winning does not give you extra points.

Yes it is ok but the ELO system would be easier to understand. Here I can't say before the game started how much points I will win or lose.
