This is definitely one area that is very vague. You would think they would have a standard and then everyone can do the same thing.
When you go to the IFPA website and go the leagues section - it lists a whole heap of different leagues. From there you can go to the various league websites and they each have their own scoring variances.
The most common is each league run a minimum of 3 machines and up to 8 machines. Everyone plays in groups of four if possible and the scores are recorded and for example you have 8 people running on 3 machines - person with the highest score gets 8 points and the person with the lowest gets 1 point. This happens for 3 different machines so it gives people a chance to get a better place on each game. Then all 3 scores of all 3 games is tallied up and then the highest scoring person gets 1st place down to 8th place. You then use the same scoring system to record against the tournament scoring.
Anyone starting late in the season or missing a comp gets zero. Say if you have 6 comps you can decide to count each persons 5 best comp results which allows you to miss a tournament.
I searched the net and a few people said a league just submits the peoples name and placings after each comp to IFPA.
To have an event registered with IFPA it needs to be listed 30 days prior to running and means you need to set all your events in advance.
Various leagues said the machines have to be levelled, preferably 3 ball, no extra ball, some opt to run when you get a extra ball to choose a flipper side and only operate that side during the extra ball. The machines can have a slight fault but if everyone agrees and it is the same for everyone then it is allowed.
If you have a windows pc / laptop you could run this software as it calculates for you.
