... You are correct, both teams were attempting to make the one ball in the side. It took them one day (Day One) to figure out how to do it and then it was on. ...
Jay -- I think they had it figured out from practice and warm-ups. For example, in the very first match (Team Match), the 1-ball was made in the side in the first 5 games by 5 different breakers. Here are the stats for making the 1-ball in the side pocket on the break (without regard to whether the break was also a foul or illegal):
Day 1 -- 21 of 38 breaks = 55%
Day 2 -- 28 of 41 breaks = 68%
Day 3 -- 21 of 39 breaks = 54%
Day 4 -- 15 of 34 breaks = 44%
Total -- 85 of 152 breaks = 56%
