[Thulium]

It seems as though most of you are missing something. You want to win to advance and the points you get are the losers. So you would need to figure not the max amount of points you can accumulate during a match, but the max amount of points you can get to beat your opponent by only 20 points assuming all balls are scored and multiplied and all robots are hanging.

This would work out as:
Your alliance - (19 x 5 + 20(bonus balls)) x 2(multiplier) + 2 hanging = 330 pts
Their alliance - (17 x 5 + 20(bonus balls)) x 2(multiplier) + 2 hanging = 310 pts
your max points = 310 pts and the win of course
