Nah you're right, you cant, the idea is the AI is learning, so it will not accurately reflect your lever's positions. It will try to lower or raise a value for you but it isnt precise. If I had made less combinations, it would've been more fun I think. Teaching them to learn dishes means they will recommend dishes which are worth more, straight away. But with 256 possible dishes, its basically pointless.
Live and learn, I'm glad you gave it a shot
