Oh dear I missed you in my quote run I'm sorry..... The score generation is explained here as well...
well that part's short so I'll quote it...
Team Total Scores
The victor of the event will be determined using each team's total score as shown on the landing pages and forum/thread headers. This score is NOT just a sum of the team's kill and heal count but rather, a weighted sum based on several factors including:
•Number of active members of each team in the killing and healing areas
The reason we decided to go with this method is because if we did not, the team with the most players would almost certainly win without any chance for the smaller team to come back. Instead of relying solely on raw numbers, we can analyze the actual team activity by looking at how active each team member is. This makes it so that even if a team has fewer people, if that team has more active players, they'll still have a reasonable chance of winning.
We are not counting those who signup and do nothing against a team's total score. The total is being determined by the users who are actually active and participating on the team. There is no predetermined result, there are no artificial numbers. Everything you see on the leaderboards is being determined by each of you, not us.
