Say you're checking your summary after winning a tournament and find out a top from the pair in second place was 'transferred' to you. If you let the Director know of the mistake you'll come in second and they'll win, what would you do? I personally wouldn't like to win that way but could it be considered a 'rub-of-the-green'? What if you hadn't checked? I have on several occasions found mistakes and reported them and have gone up or down in the positions because of this, but I know some people don't care (for example, they only check if they lose).
