Hi Gromph -- that's a good question, and I do see your point -- however, when I first put these two tournaments together, I wasn't planning on giving the winner of the Winner's Bracket two chances. I'm going to stick with that original plan, since the winner of the Loser's Bracket could have likely won a bunch of extra games to get through that extra gauntlet to reach the championship.
Hope that clears up the championship format! After all, the championship is a 4-game series with a tiebreaker if needed (basically I suppose I could have made that a best-of-5 series), so you don't have to win all your games either.
