Ha! Then why do we offset the ring gaps at assembly? After a few minutes running that would be negated as there would be no way all the rings rotate at the same speed to maintain the spacing.
Also, a true cross hatch has lines crossing each other, effectively cancelling each other out. There is no screw thread effect driving the rings to rotate.
I believe they switched to a cast crank which is substantially lighter than the original forged one. That's worth some HP.
