Does anyone know exactly how aqueduct carryover is calculated? The carryover amount never seems to be exactly 40%. I have also been experimenting with a save file and the carryover amount is not the same every time, even though all trials grow from pop 5 to pop 6, and mostly have the same amount of food in the food bucket once the aqueduct is completed. I can provide more details on these trials if needed, but was just wondering if someone is already aware of the formula.
