I haven't played the new version, but there's a good chance they cut off the information you need (likely because of us, honestly) because each person needs to see the amount of inventory going into the previous step in the supply chain. That way they can keep inventories perfectly drained except at the retailer.
If you use knowledge of the deck, you can obviously pre-solve things, but that was not an assumption here - our thing works without knowledge of the order deck.
The "new beer game" looks totally different, honestly.
