Let me try to reverse engineer part of the used tournament system of
the Men's Individual from its final result table:
- Players are required to play all rounds of the first stage. Seeded
players are required to play all rounds.
- The first stage is a 5 rounds McMahon bands system. The second stage
is a KO for four players with a game for place 3.
- The bands are 7d-5d (initial MMS 3, 41 players), 4d-3d (MMS 2, 17
players), 2d (MMS 1, 11 players), 1d-16k (MMS 0, 9 players). (Total 78
players. Note: 41 players in the top group is a possible number for 5
rounds to distinguish between places 4 and 5 by means of tiebreakers.)
- The final placement criteria are MMS - Wins - SOS - SOSOS. (Notes:
As the tied places indicate, there is no apparent further tiebreaker
after SOSOS; but how would a tie on place 4 have been broken?! This
system gives initial MMS 2 players, i.e. 3d or 4d, the chance to
qualify to the KO by winning all 5 games against on expected average
tournament-weaker opponents than the qualifying initial MMS 3 players.
Very interesting idea. However, unfortunately, initial MMS 0 or 1
players have no principle chance to qualify. The randomiser SOS -
SOSOS determined places 4 and 5 indeed.)
It is very unfortunate that the tournament system has to be reverse
engineered and has not been published for everybody before the
tournament start.

Reverse engineered part of the tournament system of the Women's
Individual: like Men's with these changes:
- Bands 6d-4d (initial MMS 2, 15 players), 3d-1d (MMS 1, 7 players),
1k-13k (MMS 0, 16 players). (Total 38 players.)
Luckily, tiebreaking was not necessary for seeding. Exactly four
players ended with MMS 6 (4 wins).

As elsewhere Herman Hiddema points out, "in the Men's individual, some
4d also started in the top group (e.g. 43. Lucas Neyrink, 38. Jesse
Savo). I believe this is the case for those 4d that are the strongest
participant from their country.".
