Superb update!

I really like that the rating is now based on points. This allows for toplists among users and what not. I just wish you would update the site more often with these kind of things ;)

I agree with Niklas, its an improvement but not by as much as I had hoped. More points should be rewarded to those people who top the original games, which have been plaved 10 000+ times. Further I was hoping the point system not to be based on your per centage score in a game but rather your position - it's easy to get 100% in a game but very hard getting the top position.

So in order not only to complain, here's an alternative way of giving points for games:

Log(Number of people played game)*Log((number of people played game)-(position))*10

Bonus could be given to the top 20 position by additional multiplication, e.g.:

1st: 10x, 2nd: 8x, 3rd: 6x, 4th: 5x, 4th: 4.5x, 5th: 4x, 6th: 3.75x, 7th: 3.5x, 8th: 3.25x, to 20th:1.05x

Example: Leading Countries of Europe, ~450 players
Log(450)*Log(450-1)*10*10= 704p

Example: 100th position of Countries of Europe
Log(450)*Log(350)*10= 67p

Example: Leading States of Australia ~15 players
Log(15)*Log(15-1)*10*10= 134p

Example: 10th place States of Australia
Log(15)*Log(15-10)*10*2= 16p

Example: Leading a game with only 3 players
Log(3)*Log(3-1)*10*10= 14p

Maths is not my forte but i agree that a game that is played 14000 times by 500 different people should be rewarded differently than a game that is played 500 times by 20 people.
Perhaps you can attribute some kind of 'special status' to games that are played by more than, say 200 players, and have been played more than, say 3000, or 5000 (or some other number) times or so. And then create a hall of fame for 'most number one spots' or 'best mean position' in those games. ;-)
And i want a stat with 'most games played overall' ;-).
As the statistics per game are temporarily disabled, i don't have an opinion on that yet.
Keep the good work up, David, we enjoy playing :)

And since Log(0) is not possible to calculate, the second term should probably be rewritten by +2 so that the lowest second term is Log(1)=1. New formula would be

Log(Number of people played game)*Log((number of people played game)-(position)+2))*10*(0-1 - from percentage of game)

I agree with last idea of Doffa, he has thought up perfect scoring. If David was able to perform it, it would be great. Otherwise i like this new change, good job David.

First of all, thanks for the feedback.

Well, basically I agree with what's been said, starting with Doffa/Niklas et al.

I still believe in a point based system, though it should of course consider relative placement as well, as so many of you have noticed and pointed out.

I'm not that keen on the suggestion of a relative target cap on what constitutes the Grand Master level, then depending on the number of games in a category. That may be a bit of a problem right now but is soon a thing of the past as more and more games gets created for the various categories.

So, in essence, I'll see about adding placement as a parameter for calculating the rating.

I guess you all know where I stand, but it would be nice to incorporate how you place. We work really hard to get those top 1-3 spots, and it would be nice to get a little extra for that. Anyone can memorize the answers and have a crappy time...
Anyway, thanks again for the site David.
(And I'm sorry if this contradicts anything previously posted...I didn't read the entire thread thoroughly)

The list of played games and your placement in the games is now available again.

I had to build a cache mechanism for it, in order not to overload the server. As with the rating system, the challenge is seldom the math or the algorithm per se, as much as getting it to work for some 200,000 requests per day.

Anyways, you can reach the game list from your profile. Click the "Different games" stat link to get to the details. Note that the stats there is cached for a couple of hours before flushed, to not risk overloading the server.

I'm currently looking into a way to consider the placement of a player, for the rating system. Let me thank all of you in this thread for pitching in with very good ideas. Thanks.

Totally cool! Way to go, David!

Thank you!
