I’m glad that our bucket chaos is permeating alternate forum posts. We’ve come to similar conclusions. The thing that was tripping me up further is that the paddles seem to have an exaggerated angle when they’re shedding water, as though they in fact tip down toward the bottom. And this could be be engineered at further loss of efficiency by making them pivot on an axis while limiting the pivot with a brace. That being said, I assume the exaggerated angles are just a combination of artistic styling and the height of the water flowing out obscuring the visibility of the paddle itself. Simple chonky paddles seem to be the best option.
