Rating change based on current ratings?

Postby rast » Thu Apr 26, 2012 12:55 pm

When a game ends, is the change in rating based on the current ratings of the players, or on their ratings when the game started?

Pro tip: drag out the games you are loosing against high level players for maximum benefit

How is that supposed to work?

I played against suckerboh, who had like 30 concurrent league games.
if i drag the game out, i get my rating after he has beaten 29 other people.
i get more increase to my rating than if i lost the game quickly.
however it matters little, and is also a rare scenario.

Yeah, it doesn't work except in very specific situations that you have little control over. I feel like it can just as easily backfire or be completely useless, and then all you did was make an ass of yourself by stalling games pointlessly.

As a general rule, don't stall. It's a dick move.

So you it seems like you "should" stall against still-rising players who are clearly much better than their current rating, but against established good players who have wins and losses there is no point.

If you're in a situation where you're about to win game A, and sure to lose game B, it's better to resign in B before you get your win in A.

Suppose you're about to win in two different games -- is it better to get the win against the higher rated opponent first or second? Or does it not matter?

I don't think it matters. I haven't seen the exact code for the rating system though, so maybe Glen would have to answer that.

The only way it matters for sure is if your opponent's rating was to go up or down in the meantime. If you see that one of your opponents you're losing to is about to win a game, then it might be your to advantage to let them win before you resign the game, so you won't lose as many points. In that one single situation, it might benefit you to stall -- but seriously, you might gain like 2 extra points. If you want to use gamesmanship and stall games for almost negligible point totals, then I guess that's up to you. :?

The real question is: are there better things to do than to be overly concerned with league ratings which consistently does not accurately reflect the skill level of each player?

I still love you! Tonight, your true love will realize they truly miss you. You will get a shock of a lifetime tomorrow. If you break the chain, you will be cursed with relationship problems for the next 2 years. Karma's a bitch, I know. If there is someone you love, and can't get them out of your mind, repost this paragraph as "I still Love you"

...play AWBW? you're right. BRB, going to make artwork for deaf women.

Well, if it was perfectly accurate, there'd be no point in trying to game it...

Gaming the system is a way of begging for the system to be changed.
This rating system was not designed for multiple simultaneous games long enough for ratings to change.
But if the rating change was based on when the game started, stalling would be absolutely pointless.
Is this what you want?

Nope, that'd be far more abusable.

Nothing needs to be changed. It's OK if players take small advantages for small short term gains -- in the long run, if they keep playing, their rating will reflect their skill.

For example, suppose I have 5 games I'm about to win and 5 I'm about to lose. If instead of finishing them in random order, I take my own advice and resign 5 before winning the other 5, my rating will be better. But then when my NEXT wave of games finish, I'll be gaining a little less on the wins and losing a little more on the losses.

Also, I'm pretty sure it wouldn't matter which order you win or lose in, your rating would be the same.
