If you are using the word "efficiency" in the usual sense of power_out/power_in, the only loss in efficiency of mecanum wheels compared to standard wheels in the forward direction would be due to roller motion caused by roller axial free play or compliance of the flooring surface or the roller material or flexing of the vehicle. I don't think this amounts to a 30% loss, but I don't have any test data to prove it. In the ideal case (no roller axial free play, no roller bearing friction, no squeezing/stretching of the carpet or vehicle), mecanums have the same efficiency in the forward direction as standard wheels.
