Since my previous Liga IV ascended 3: the champion and the other 2 teams best record of the remaining 15.
But the number of leagues IV Utopia first season was higher than 64, so at most, 3 were promoted.
This season, however, to be exact numbers (16 lower divisions to cover 64 places in the top league), is as Brutus says, and amount to 4 per league.
