C IL | Kagen, I've been thinking about this too. I think Nafziger made a good technical argument regarding definitions, pointing out that yield is the weight of corn per acre, and that test weight just describes the bulk density of corn harvested from that acre.
As a farmer, though, I totally get the point that, had my corn not been frosted/whatever, and I had more sugar convert to starch, I would have had more pounds of corn/acre (higher yield), and when harvested it would have been described as having a higher test weight. The low test weight I'm seeing as more a symptom of yield loss than a cause.
I'd also note (way too many physics classes)
yield = mass (weight),
bushels = volume, and
density (test weight) = (mass/volume)
so, if the volume in the trailer is the same (up to the tarp bows), are you seeing identical net pounds on the ticket between 56tw and 52tw corn? If not seeing different net weights, that would be some wicked cool physics.
