If you keep loosing a lot of games your income suffers more than with loss away and win at home. Bigger winning streak nets you more income.
You want the last game not to matter. I think that's just plain wrong. Like I said in your suggestion thread it's all about the ability to evaluate the schedule. You know when the prices change. Evaluate those games that have the same ticket pricing, then set your prices depending on games you win before your home game. This is called maximizing arena income. If you don't like the income flucktuation. You can set prices that bring full house, weather you win or lose. This way you get guaranteed income (although smaller) and can always count on it. Really evaluating 7-8 games is not something undoable, like you are suggesting here.
