Nice work, Lizzy! Sounds like you need a well deserved vacation now, after all the figuring.
I can't see the "pH effects" being worthwhile in a dog or cat, so I tend to keep the veggies to close to what a wolf might get, after shaking the rumen contents of the caribou all over the ground before diving in. Maybe 10%?
I think you could be a math/sourcing consultant, having put all the thought into it that you did! Ready to hang out your shingle?
