I have to say that it seems really odd to give double dipping and award points just because a portion of the league is in that state. Even stranger since a league does not require you to play in every event. This is counter intuitive to building competitive pinball events in your own state if each year people that have not even set foot in your home state are getting points.
Playing devils advocate... If I set up an intertstate league where I travelled to various states and hosted league at friends houses, then every person from each state would be allowed to get points in every single state for SCS purposes?
I could start and interstate league which has events in WI, IL, IN, MI, MN, IA, CO, and PA just with the help of a few buddies. I could also leverage a few route locations to add some states.
