I didn't really figure it out. I use the food in addition to dried kibble from Fromm for one of my dogs, the picky one. He's a shitzu-poodle cross of about 15lbs and doesn't eat very much. When I feed only the food I make, I give him about a half cup twice per day. I just made sure I had a decent balance of meat and vegetables in there along with the fish oil and vitamins which I added at feeding time.

His weight has never really shifted so I figured it was enough. Right now he's back on Fromm since he's being less picky. The next time I make food I'm going to try putting my other dog on it exclusively for that batch. He's a 38lbs basset-cross that will inhale anything and could stand to lose some weight. I think 32lbs would be good for him.
