crack those chains into smaller portions. So, a crackspread is effectively the difference between the value of the barrel of finished refined product, so let's say in this case diesel, and the barrel of crude oil that would go into produce it. Now, refineries can't just turn a barrel of crude oil into a barrel of diesel, unfortunately, given our current our current prices. It's all turns into these fractions, this kind of rainbow spectrum of different products. So, essentially a refinery margin at the end of the day is a weighted average of those crackspreads adjusted for other
