No, this contraption had a lot of value that drop feeding does not. I have spent hours drop feeding, and I never could get the same breakthrough.
The cool thing about the contraption is that you can freeze or go as slowly as you want, and he is standing 3 feet away able to make corrections.
I'm a big fan of drop feeding, though, so when the weather clears I will go out and see try to get some muscle memory on what I learned.
