One additional item I noticed, you are awarding 5 points for every elimination match but teams should only receive the match points if they will the series. As stated here:

This attribute measures Team performance as part of an Alliance.
All Teams on the Alliance winning a particular playoff series, who participate in matches with their robots, receive 5 points per match won. In practice, this will usually mean Teams will receive 10 points at each of the Quarter Final, Semi-Final, and Final levels, unless a backup robot is called in to play
