Which pair will be the first to achieve 0 up and down runs.
Rules
You start by sprinting up and down the width of the hall 5 times as fast as possible.
Then you shoot 10 times within 2 meters and count how many times you score. You shoot alternately, so 5 times each.
If you have scored 5 or more times -half your number of single sprints- then you may sprint up and down the hall one less time, so 4 times.
Then you start shooting again and count how many times you score. If this is half or more than the number of times you have run, then you are allowed another up and down.
