I also see a couple of teams on your list that I know who's scores are way to high.

As I have said from the beginning the algorithm just won't work unless the penalties are somehow added in. They are just to important to this years game.
I don't think you're following what Bongle and others are doing. They're not calculating simple averages. They're using basic linear algebra to calculate the average expected value of pure points contributed to the alliance by a single team. This is used by setting up a system of equations which sum to the amount points scored at the regional. Since penalties are already removed from the final scores of all matches, this method takes them into account. The penalties are already "added in". This method is a far more accurate predictor of a team's contribution then just looking at a simple mean. Naturally you team's result is going to be lower than your average score, because this statistic is just looking at your team's contribution.
