To figure out how many new games you're going to get, take a look at the "Group size" column for the tournament. You will be playing two games against each player in your group.
Fore example, if the group size is 2, you would be playing 2 games (the group would consist of just you and another member).
If the group size is 4, then your group would consist of you and three other members - you would be playing two games against each of those three members, which means 3*2 = 6 games.
So you can calculate the number of games you are going to receive by the formula: (Group size - 1) * 2
EDIT: Seeing that you're new here, and haven't yet joined a clan, I recommend taking a look at this thread:
I'd gladly welcome you to the Hardcore Pawn Stars, only since I see that you tend to use 1.e4, that would mean a little foray into new opening territory for you...
