I am just wondering can anyone in simple man's terms explain how a IFPA tournament scoring system works to allow for heats in one comp with say 6 comps in total for a tournament.

I am wanting to assist in setting up on in Aus and a little confused after visiting the IFPA site.

Say 10 - 15 people in a comp

How many machines are required?
How heats are run and what type?
How is the scoring system calculated for heats and then that comp day towards a rated tournament?

Any help would be much appreciated.

I found some good info here
