There is inadequate evidence here to come to any conclusion.
It would be irresponsible of me to claim that I knew all the farmer's capabilities, costs, risks, weather forecasts, crop options, crop rotation requirements, etc. If I did that, I'd be guilty of exactly the same mistake as OP.
Noise is not signal. Noise is the enemy.
You did a great job of noisily pointing out that the parent is noisy, without generating much if any signal yourself.
You don't have to provide a conclusion, just presenting a theory about how to apply those data points that you keep rattling off would be something constructive, a starting point.
Thing is, that would be hard and expose something you created to criticism. It's much easier to simply sit back and poke holes in someone else's flawed theory while alluding to an ability to construct a better one yet demonstrating absolutely nothing.
