I have seen your math but your math doesn’t make any sense since you are doing your math on the wrong assumptions. You assume that the ourworldindata chart shows that at the end 17% of the weight of the global soy productions ends up as oil but that’s not what this chart is showing.
What it’s actually showing is that for example if we produced 100kg of soy globally 13.2kg of of that produced soy is used to make oil. Which means that the actual weight of the oil is 2.64kg in this example (assuming it is correct that soybeans are 20% oil, and we extract it perfectly)
the ourworldindata chart has another 4% of oil at the bottom.
Are you talking about the Industry percentage? That’s not oil. But even so your math is still wrong as I’ve demonstrated in my example above.
