If there are five or fewer 2-game winners and less than 8 unique
winners with 35 or fewer entrants, then those players will advance to a
four or five player final. (Five advancing if there are exactly five
two-game winners). Remaining spots in the 4-player final will be filled
by players with one win and the best second result in the heats.
Otherwise:
With 12 or fewer unique winners, there will be three 4-player games in
the semi-finals. The three winners and the closest second place (in
terms of percentage of winner's score) will advance to a four-player
final.
With more than 12 unique winners, the top 16 players will play 4
four-player games in the semis, winners advancing to a four-player
final.
