I agree.
Actually, I don't think you understand what a "major" or "minor" is in gaming terms.
Major: Something the size of Evo or NEC. Multiple games with huge turnouts. Evo has set the bar for SFIV majors since it had over 1000 entrants. Also, prize pots, if your prize pot is exceeding over $1000 per game then you could consider it a major. Majors also usually are very fancy and are something that everyone wants to fly out to from out of state or out of country.
Minor: Something along the lines of a regional. Turn out per games still exceeds at least double the turn out for a small biweekly tourney and people still come from out of state for it. Prize pots are still pretty high, at least over $300 per game.
The tourneys that have been thrown at FFA, Denjin, AI, etc are not along the lines of these, Denjin and AI refer to them as ranking battles but in the end you are rewarded for getting top 3 in the ranks with some sort of prize. You could call the FFA ones casual tourneys (?) since it's just something that happens every other weekend.
