In the league, I explained it in a message post:If you click on full standings, it gives you a breakdown. Its set up, to divide each stat, so that theoretically the top guy will ge 19 points, and the bottom guy gets 1 ( 10.5 each if two are tied for 10th/9th) And, the plus and minus you see on the main page is what you acheived in the last night.. So, if you are tops in goals already, and second in assists, if you score 20 goals in one night, it wont matter, because you cant move up any, and then if the next guy gets 1 assist ahead of you, you still drop by 1 point..
I dunno if that was helpful at all.. But, thats my best try at an explanation.
Now, if that explanation is too random, or vague, let me know, and I can give a better shot at it
