Here is the new point formula if you don't have the calculator:
Old point system:
Points = (Calories / 50) + (Fat grams / 12) + min { Fiber grams, 4} / 5)
The "min" part means the number of grams of dietary fiber or 4, whichever is smaller.
Let's take an example:
McDonald's Big Mac (214g)
Points = 540 Calories / 50 + (29 Fat grams / 12) + 3 Fiber grams / 4)
Points = 10.8 + 2.42 + 0.75
Points = 13.97
Rounded Points = 14
Points Plus = (Protein / 10.9) +( Carbohydrates / 9.2) + (Fat / 3.9) + (Fiber / 35) (all amounts are in grams).
Big Mac:
Points Plus = 25/10.9 + 45/9.2 + 29/3.9 + 3/35
Points Plus = 2.29 + 4.89 + 7.44 + 0.09
Points Plus = 14.71
(It's described in intimate detail on the US Patent Database (#6,040,531).)
