How is efficiency measured under Parallel Path?
A standard flux analysis sets 400% as the ideal maximum of force manifested relative to electric input. If we define 400% as our ideal expectation for the operation of the system, then that marker point becomes 100%. For example, if a real device manifested 350% more force than was electrically inputted, that would be (350/400)=87.5%. So really, no PP system is ever over 100% efficient, where the terms of reference are properly understood.
