Here in MI there are no B,A and Masters divisions. They break it down into 2 categories,,,,,the "open" division and the "masters" division.
That works for team events and single events.
If you are a open division player on a masters team and place high into the money,,,you will be playing in the masters events for the next 3 years following.
That goes for the single events also.
A masters team is any team that has at least 2 master players on it,,,but can be all five.
A master player can play in the open team event ,,if he is the only master player on the team. And the players are from his division.
I know this dont answer your question but may give a idea of how they do it.lol
