Sounds like you have a plan-- just wanted to throw something out there (not to confuse you more or anything, LOL.)
A physician friend of mine-raw-feeder (whom is retired and does nothing but research and document human and dog health these days), along with a natural and raw-fed breeder for over 30 years, have both come to the conclusion that the "80/10/10" is kinda bogus. In other words, way too much organ is given in that ratio, and could cause some issues down the road (not to mention very loose stools.) They feed prgans maybe once or twice a month- and their dogs are thriving. I have also backed off on the organs- as well as stressing so much over the "optimum ratio" and have adopted a more lenient and sane philosophy: "balance over time."
