The current system of consecutive points, with home and away games

The current system of consecutive points, with home and away games, was only adopted in 2003. Until then, the championship lacked standardization. But the changes didn't stop there. In 2006, the competition had 20 participating teams and, in 2007, it was defined that they would face each other in 38 rounds, with 10 matches each, played between April and December.
