Or we could have all the teams listed randomly all tied for first until the first challenge is over. so it would be like this....
1st Team 1 (0,0)
1st Team 2 (0,0)
1st Team 3 (0,0)
1st Team 4 (0,0)
1st Team 5 (0,0)
After the first challenge (between team 3(win) and 4(lose))...
1st Team 3 (1,0)
2nd Team 1 (0,0)
2nd Team 2 (0,0)
2nd Team 5 (0,0)
3rd Team 4 (0,1)
