The game manual says,
Two teams are invited from each country, the champion of the National Tournament, and the winner of the country's division I league. If a single team wins both contests, they are the sole invitee from their country. In addition, the champions of all previous B3 tournaments are invited to participate in perpetuity.*
How about the champion of tier1 buzzerbeater madness? This team
(56221) is the champion of tier1 BBM in S57, and is invited to B3 this season.
To reach 128 teams, the remaining spots will be filled by the top ranked teams who were runner-ups in their country's National Tournament, their country's division I league championship, or the previous season's B3 and BBM Tier 1 tournaments.
What is "their country's division I league championship"? Is it the final of the playoffs in division I league?
Let the set S1 consist of the runner-up of B3, the runner-up of tier1 BBM, all runner-ups of national tournament, and all runner-ups of division I league in previous season,
and the set S2 consist of all teams in B3, all teams in tier1 BBM, all runner-ups of national tournament, and all runner-ups of division I league in previous season.
Does it mean that the remaining spots are filled by the top ranked team in S1 set or are filled by the top ranked team in S2 set? Thank you.
