Torque and RPM Graph for Castle Creation products ?

Looks to me like the torque is left to right on the graph.Which means the more load they put it under the lower the efficiency went.Which is to be expected. Looks like it reached about 34 oz/in of torque,with no rpm fall off.But it was down to 50% efficiency.Now if we only had the same graph for every other motor we could interpret some results.
