The rule is standard and is typically applied as a second tiebreaker in most sports.
Sorry, this is
not true (At least for the US, I dont know what sports they play in bulgaria...)
In football (American football), head-to-head is the first tiebreaker, then division records, then common games, then conference records. In the case of BB, the "divisions" are the "conferences", because BB doesnt divide the conferences by locations (east, north, south, etc.).
The teams' net points (total points scored) do not come into play until the 9th tiebreaker.In baseball, for a division tie, they use head-to-head first, then intradivision games, then higher winning percentage in the last half of the season, then the winning percentage in the last half of the season +1 game, last half +2 games, etc.
For a wildcard, a tiebreaker game is used.
Runs scored are not even considered in this tiebreaker.For basketball, it is H2H, then division record, conference record, record against teams that qualified for playoffs, points differential.
Again, net points are not considered in the tiebreaker either.These are the three major/most popular/most competitive team sports in the US, and from high school (and below) to professional level, tiebreakers rarely involve net points, because it unfairly favors the better offensive team.
From my experience (I've played four team sports competitively, H2H, division records, and one game playoffs have always decided a tiebreaker for the postseason.)
As for BB, the closest comparison is the NBA (being basketball), which does not consider total points for tiebreakers. If they did, if teams like the Spurs or Celtics faced this situation, they would be unfairly screwed over.
