Incredibly helpful point about the iterative aspect. A softer benefit of the chaining idea you have is that you could build an amusing narrative like pizzas eaten annually in the U.S. -> gallons of milk used -> cows dedicated just to pizza production. And if a user was ~30% low on one stage, they'd know to overestimate slightly on the next. Thanks!
