Positions by round
The table lists the positions of teams after each week of matches. In order to preserve chronological evolvements, any postponed matches are not included to the round at which they were originally scheduled, but added to the full round they were played immediately afterwards. For example, if a match is scheduled for matchday 13, but then postponed and played between days 16 and 17, it will be added to the standings for day 16. Source: BDFútbol
