Hmm...

I think the perfect score should be 10, because it's neat, and it produces more roundable numbers.

Also, I think the defending team's score is lowest when they lose barely after the half-time mark, and their score increases when they lose much later into the game, which is fair. I've noticed that the attacking team gets 0 points when they lose, no matter how far they get, which would be a shame for the attacking team if they lose both rounds, and IMHO this is a problem which needs to be fixed.

I've already created a spreadsheet using Flash's system, and will upload it on the JDC files section ASAP. Take a look at it.
