Questions about Ranking Battle Seasons, How to run them, etc


I’d like to hold a series of tournaments for my local scene for both AE and MvC3 before AE 2012 and UMvC3 comes out. However, I’m not entirely too sure how points are distributed amongst top 8 and just how many tournaments are necessary for a “legitimate” season.

My ideas for a ranking battle so far is:

[]4 season tournaments + 1 wildcard tournament + 1 playoffs tournament
] Point distribution is as follows:
1st: 8 points
2nd: 7
3rd: 6
4th: 5
5th: 4
5th: 4
7th: 2
7th: 2
1 point for everybody else who joined.
[*]The top 7 players with the most points from the first 4 seasons make it to the playoffs. On the day of the playoffs, there’ll be a wildcard tournament, and the winner of that tourney gets 8th seed. Then the playoffs is a seeded double elim tourney where winner takes the title.
Any of you seasoned tournament organizers out there have any suggestions for how I should run this seasons?
