This exercise was establishing the "rules of the game". I don't understand the technicals, but hopefully most of the rules are in our favor. The "GAME" still has to be played (at trial )to determine a winner. If the rules are moderately in our favor then we have a good chance to win, if not then we must have an exceptional game to win. The more scholarly posters may have a better explanation..... HR, SH and I would like to hear from the professor...downside?
