Unfortunately just the one game so far still.

Well, I guess once you play more games, you can let us know if the strengths are as random as you suggest.

Well when it's 10am on a Sunday here and 2am on a Monday there...

Also since handicap games aren't rated games there, I don't think ranks are at all stone differences, so that also makes it hard to do any direct comparison where KGS has quite a number of ranked handicap games.

Yes, I agree. They are hard to compare directly.

I would recommend you start a new account and set your rank to 3k and see how you do from there. At the lower ranks there are a lot of sandbaggers.

I started a new account just now and won my first game as 1 dan. Ain't that a kick.

Congrats!

Your rank on Tygem depends on your fighting ability.
One of my students, who can fight well, is 2k on KGS and 1d on Tygem. On 2k KGS level it's much harder for him to win games.
On Tygem you have to fight in every game!

It seems to me that 1 stone of rank on KGS is more like 2 ranks on Tygem.
That is, each 'rank' on Tygem is actually worth significantly less than 1 stone of handicap.


As a result the tygem scale is far more spread out.
Dan players are usually ranked higher on Tygem than kgs, since the Tygem ranks go up to 9d.

But for kyu players, we are ranked lower on Tygem.
I'm 8k on KGS but 12k on Tygem, with about a 50% win rate at that level.


I dont think its 'fighting skill' as much as it is a mathematical property of how Tygem calculated ratings compared to how KGS calculates them.

Does tygem calculate anything in reality? it just checks to see if you pass some won # threshold in your last 20 games.

Yes, that is what it calculates.

I don't call that a calculation because I think of a rating system with actual maths behind it

noun
noun: calculation; plural noun: calculations

a mathematical determination of the size or number of something.

Tygem mathematically calculates someone's rank, based their past games, as you described. You may not agree with the calculation, or perhaps you think it's too simple. But it determines a rank based on your performance in games.

In this way does tygem actually have a "rating" to calculate?

Your rating is your rank. Since the calculation is simpler than other methods, it's not necessary to add in additional numbers. If you want to think of a numerical rating like ELO or WHR, you can just make arbitrary values (eg. 1d=100, 2d=200, 3d=300, etc.).

The point is, this rank/rating is calculated based on game results, even if the method of calculation is simpler than more complicated models.

I think Tygem has rating points as well. They just don't have any influence on your rank.
