How is seeding and group placement determined in multi-group tournaments?
For multi-group tournaments, players are placed into groups starting with the highest rated player sequentially down to the lowest rated player.
For example, in a 25-player tournament with 5 groups and 5 players in each group, the top rated player goes into Group #1, 2nd highest rated player into Group #2, 3rd highest rated player into Group #3, and so on.
After all groups have one player, it runs the opposite direction. So in this example, Group #5 would have the 5th and 6th highest rated players, Group #4 would have the 7th, Group #3 would have the 8th, etc.
