The various methods for measuring rear hub power indicate deliverd
power but the rider also has to provide for power train losses.
Difference may be small but useful to know.
I noted that one method would be to telemeter pedal force, with one
method being strain gauges on the cranks. Producing mean power from
the delivered pulsating power would be "easy enough" [tm].
