Thoughts
People talk about feedback loops as a way to avoid accumulating error, but I don't. I see a feedback loop as removing the need for precision
If you have a feedback loop, you don't need precision. Think of learning to bowl. If you want to hit the pins, you could add more precision to your throw. Or, you could put the rails up. The rails act as a feedback loop, redirecting the ball if it goes too far from the center, and allowing you to hit the pins even without precision.
