Results from my personal testing:

Brighton: (underdog)
1,63 points per game
1,74 goals scored per game
1,42 goals conceded per game

Parma: (underdog)
1,76 points per game
1,71 goals scored per game
1,34 goals conceded per game

Note: Parma fell victim to the AI adapting during testing. After 22 games, they were sitting on top of the table with 48 points. This is something I tend to see quite often in testing recently, when massive underdogs do incredibly well with a tactic from the very beginning.

Celta Vigo: (mid-table team)
2,21 points per game
1,87 goals scored per game
1,00 goals conceded per game
