I've literally seen contracts that define promise n% of "____ gross", where "____" is some inconspicuous seeming word, but they then define that phase in such a way that it does not even remotely correspond to the actual gross. So knowing that you want gross instead of net is nowhere near good enough to avoid getting screwed. (In the case I am referring to a book author who sold movie rights was screwed over by a contract specifically misworded to sound like she would be getting a percent of of gross, when the actual definition used was much closer to that of net).
