I think it's (kills - errors) / total attempts. If your errors are greater than your kills, you get a negative percentage.
Ahhh that makes sense.
12-8 Iowa State and Hockaday is on the floor grabbing her left knee after a kill. Her knee completely buckled when she landed.
Ok, they just showed the replay...it bent the wrong direction. Getting help from the trainers to get off. No weight on it period. If I had to venture a guess, she just completely destroyed her left knee.
