Ok, thanks! I was just curious if the batter code used CS or if it
used the raw values that CS is calculated from - it does make a slight
difference as a unit who's CS is high because of training might behave
differently to one which is high because of equipment, or it might
not, depending on how it works. (Well, I assume it's actually
somewhere in between, there would be no point having separate values
if they weren't used separately at some point.)
