Whoa, that sounds like a pretty harsh response to Moose. Give the guy a chance. Perhaps if you had mentioned that you had tried that particular formula, or you had posted the formula you actually used, he wouldn't have posted the "obvious" answer to your question.
So, the thing to do, I would say, is post your formula and let's see if we can see what might be wrong. If it looks correct, I'd say to then attach to a post a simple tournament where you see the points awarded incorrectly, and then someone here (me, for example) can try to track down what's going on.
