A light short story with a social commentary. Sounds boring and clichéd but try it.

Farida concentrated hard this time. She'd win. There was a cry of triumph from her brother as he shot her down in flames. Elder brothers she decided were the pits. She'd read the manual about the game. It talked about how statistics were used to decide what happened when someone was shot.

After class she asked her teacher about statistics he found her a book that explained the subject. If she used only 85% of the available firepower when she fired her phasers she zapped the opposition most of the time but more importantly she still had power left over to tackle another battleship without having to return to base to recharge them.
