A computer would be helpful.

Ours is a Missouri 8-Ball rules league. So it isn't too confusing. The APA 8-Ball rules are way too confusing. Rather than keep track of each win/loss, they keep track of every shot.

Hang in there, sounds like you guys are doing quite well.
In pool it seems like we all click one season and nosedive the next. Up, down, up, down, and so on.
My son started playing in the league too. His team had a bad first season and they won it all the next. He won the final game of the season that put his team on top and won the last game of the playoffs.
He and his team are having a bad start to this season now. He just needs to get used to the fact that you can't win them all. It is nice playing with him every week. We usually practice together two or three times a week too.
