while i agree it is a good idea, its not really gracious professionalism... and since you already crossed the line, it would be hard to trust the other team unless you know the people on it (maybe a highschool right next to yours or something)

actually getting the boxes perfectly set up would be kinda hard, and when one box is counted because its corner is in, the other team might whine about how you broke the deal and no one should trust you and blah blah blah

all in all i think ties are more trouble than their worth (fortunately, or some teams can get an easy ticket to the top)
