The actual calculation looks like this:
(((last year standing - this year standing) x 3) + ((last year Ave - this year Ave) x 4) + ((this year points - last year points) / this year games) + (((this year black chips x 6) + (this year green chips x 4) + (this year red chips x 2)) - ((last year black chips x 6) + (last year green chips x 4) + (last year red chips x 2))) - ((this year games - last year games) x 10)) / 10
