Accelerating the cranks from 90 to 130 RPM is the only thing that will take any power, although you are correct it will be small.
I cannot help you at this point, you should do some actual research and learn some physics, a rotating object does have centripetal acceleration, this must be counteracted, if there is less weight, then there is less force to be counteracted, this explains why feet sometimes slide off platform pedals, because the foots linear momentum is tangential to the crank, therefore the cyclist must accelerate there foot towards the bb to pedal in a circle. If you dont like my calculation, I can respect that but please do a better one that doesnt ignore all relevant forces
