Life In 19x19

Sounds like a very good system to me. Thanks very much Herman!

I've corrected the links for the old BGA promotions committee there - it is http://www.britgo.org/history/gradcomm.html. The points system was created by Andrew Daly and was in operation for about 25-30 years.

Interesting system, I like it. What about demotion?

In practice, demotion only happens if a player asks for that himself. The nice thing about this system is that a dan grade becomes somehow a nice "title" (promotion norms are relatively strict). The downside is, of course, that there are a few (usually older) players that have been underperforming for their grade for many years. I think this is not so bad though, because many players apply for demotion anyway after a sufficient number of bad results.

Sankyu Herman. Nice system, but probably suitable for limited populations only. (Most European countries are small enough, however.)

I've also read about the finnish system... it seems to be awfully complicated and I wonder how many players are really promoted that way? I.e. why do they wait so long for tournaments to get promoted, when basically the local club can do it by itself irrespective of tournament results and GoR?

However, I would like to see the dutch system (for dan players) explained here. Maybe, it is a viable alternative to rating magic.

Actually I guess the first change was the introduction of tournament classes, after that initial change everything stayed the same. If you suggested a change, you were told that it would involve changing something. Then, yes, after 10 years along came a small change to one of the parameters. Since that changed the average rating of a shodan has been crawling upwards instead of downwards..

Isn't that fine, in about 30 years everything will be aligned to rating math again.

In the meantime we can comfort ourselves with the knowledge that self ranking is better in predicting results than rating anyway (acc. to andre engels case study for dutch kyu players). In countries with more emphasis on "earned" ranks, we will probably see that their ranks are not very predictive for the results at all.
