WRC seeding for the preliminary round… (tables and stuff)

For those interested in who will be paying who, the staff at osamuko.com would like to both explain how and who will play who, given the drawing mechanism and who got what number.

Essentially, players were divided into 4 groups. Players may not play against other players from the same country, with the obvious exception of Japan (and France to help smooth organization). Players will play each other on locked cycles, where… Table N will have players (N, N+30, N+60, N+90) facing off. When that match is done, each player will move forward (0, 1, 2, 3) tables down. A number with this formula is essentially bound by its group of 30, so that (N, N+30-1K, N+60-2K, N+90-3*K) will take the remainder of a division of 30 and return the value in the right block. (A table with (9, 33, 87, 111) would exist in Hanchan 7 as an example.)

Anyways, a player can easily know which table he is going to play at as well as some of the Japanese pros they will play against. For a player to know if they are playing another player, they can either use the grid above or do some funky math on the fly to figure it out. Countries have been divided into the following groups:

1: Japan*.
2: Japan*, Australia, Canada, China, Italy, Russia, Singapore, South Korea.
3: France*, Austria, Denmark, Germany, Netherlands, Poland, Slovakia, Switzerland, Ukraine.
4: France*, Czech Republic, Finland, Spain, Sweden, United Kingdom, United States.

This definitely qualifies as a wall of text, but everything you should need to know is here! In the oft chance I made a mistake, let me know right here. I did my best to link pictures of the starting grids, the math wizardry behind it and kept player names spelled as on the WRC website.

We would like to thank everybody involved behind the scenes and all players for their participation.

EDIT: Iapetus was right, and I should not update stuff at 4am. I should have known since in Game 8, I should have been on table 1.

4 thoughts on “WRC seeding for the preliminary round… (tables and stuff)

  1. Sorry, but this doesn’t look right; it contradicts the official lists. I think you made a simple sign error.

    Say, in table 5 in hanchan 1 play players 5,35,65,95.

    The players who should play there in hanchan 2 are 5, 34, 63, 92.

    Whereas you have 5, 36, 67, 98.

    And so on. Basically, the direction of player movement is the inverse of what it should be. You got everything else right.

    1. You are correct. Under the influence of sleep deprivation, I cycled wrongly. Players move forward in tables, but since the tables are stationary, they are coming from further back, thus why you need the subtraction in the formula. Should be fixed now.

  2. Great work! I have a question: so the purpose of grouping countries into 4 groups is to minimize players from the same country playing each other as much as possible (except for Japan and France, obviously)?
