Which is like comparing a person on a bike to a leopard. The numbers I saw would be dramatically higher if sampling in freefall. Methodologies aim to average

Which is like comparing a person on a bike to a leopard. The numbers I saw would be dramatically higher if sampling in freefall. Methodologies aim to average out those effects. It's easy enough to lie with disingenuous comparisons. It just doesn't make sense that something that needs to spin large rotors at supersonic speeds is more efficient than something that spins much smaller rotors.
