> The milk pricing tool consumed the feed tool’s output as one of its cost inputs. The format change hadn’t broken the connection — the data still flowed — but it had caused the pricing tool to misparse one field, reading a per-head cost as a per-hundredweight cost, which made the feed expenses look much higher than they were, which made the margin calculations come out lower, which made the recommended prices drop. “You changed your feed tool,” Tom said.

“Yeah, I updated the silage ratios. What does that have to do with milk prices?”

“Everything.”

He showed Ethan the chain: feed tool regenerated → output format shifted → pricing tool misparsed → margins calculated wrong → prices dropped → contracts auto-negotiated at below-market rates. Five links, each one individually innocuous, collectively costing Ethan roughly $14,000.

Ethan looked ill.

I've re-read this a few times now, and can't work out how the interpreted price of feed going up and the interpreted margins going down results in a program setting lower prices on the resulting milk? I feel like this must have gotten reversed in the author's mind, since it's not like it's a typo, there are multiple references in the story for this cause and effect. Am I missing something?
