The objective reality is 20-24 teams of 4 people each,
with either 4 groups of 5 teams = 8 games (rounds) = 16 weeks, followed by 1/4 (approximately 5 weeks each stage of the playoffs);
or 6 groups of 4 teams = 6 games (rounds) = 12 weeks, but then starting from the 1/8 stage (approximately 5 weeks each stage)
