I weight the catagories with the best picture/director acting awards and animated all worth 7 points. The screenplays are worth 6 points each, music categories 5 points...and they go down to 1 point each for the shorts and sound catagories.
I have been running the Oscar pool at my Oscar parties since the mid 90's and average about 30 people a year these days.
Last year, I also had everyone vote on Best Picture by ranking the nominees 1 -10 and showed everyone how the best picture is determined by the academy during one of the commercial breaks. Avatar was our selection for Best Picture.
