Yes, but it depends on how the frame flexes under load- which comes back to how the carbon is laid down.Remember Newton's third law? Every action has an equal and opposite reaction? If the frame flexes, it will flex back. Where does the energy go? Not into heat, so into the return flex of the frame.
If a frame deflects laterally, it will bounce back laterally, wasting some of the input energy intended for forward propulsion.
