They described a lot of data. Then, toward the end, they say:

"These loss estimates reflect national averages; actual costs of production and returns vary by region, management decisions and ownership structure. For example, producers who own their farmland may face lower total costs by avoiding cash rental expenses, resulting in higher returns."

So, can we trust this to say what it appears to be saying? Or might it be meaningless like many broad averages, and we should use more specific data that includes supplier behaviors?
