Yes, I agree. Although I did not see it, I suspect it may be rather a hindrance because if you have it pre-casted in a concave shape, without the blade being stretchable, the blade loses its lengthwise flexibility (as you can see in ADR's photos with a paper sheet) and rather moves the water downward (at the down kick) instead of backward.
