Version 0.9.2 Bugs
TC scoring is bullet_damage / number_of_rounds. Which produces an output between 0 and 100 (not 0.0 and 1.0).
The your_score / (your_score + enemy_score) is a percent index. It can't be used with bullet damage where one of the robots does not fire (which is what happens in a TC). The reference robot (the one moving) will never have any bullet damage.
