Life In 19x19

Interesting plot.

I can see Sumire and Asami

I can also see Sugiuchi.

Nishioka Masao (former) 2-dan and with a record of 18-13 in 2021, is now 3-dan, based on prize money. Perhaps it's all the prizes while he was 2-dan.

So... I am just curious as to how this works

https://www.nihonkiin.or.jp/player/rank.html has the Japanese promotion rules. As you can see, there are two things about prize promotion:

1) Only the fees earned in top 7 tournaments count for promotion
2) If you got promoted that year based on wins, you cannot be promoted by prize money

So, Sumire was not eligible for prize money promotion in 2021 since she got already got promoted to 2 dan by wins. In 2022 she will get two chances for promotion to 3d: wins or prize money

In the plot above it is obviously a non-linear relationship. There is at least one outlier, too. However, the fact the all the players with high number of games are young. I venture that that is due to young players wanting to be promoted but not being able to do well in top seven titles.

I saw a Tweet that reminded me of this post. Ichiriki working hard to make that money.



Just kidding. It's actually a nice give-away.
