Hello,
I'm a pool organizer (for the 15 last years). I have tryed a lot of different ways, but the best one for me is 1 =1 meaning that 1 =goal is good for 1 point and 1 pass is also good for 1 point
For the Golies: 2 points for a victory in regular time, 1 point if a tie match (before shoot out) and 3 extra points if no goals allowed.
By the way, take a look at poolerkits.com for a great way to improve your pool. I have been using it for my last 3 pools.The method is easy to download and it's worth it.
Hope that this post will help you. feel free to ask more advise if necessary
