what i've found is that 1 cup (of fat free or the 94% stuff etc etc) is 1 point... It seems to stick to that even if you have 7 cups... 7cups = 7 points.
10 = 10..
I usually get the individual 100 cal packs. They're on special the most, and its easier to not worry about overindulging. You have a small packet, you can eat it all
