Gearbox friction model

I'm making a gearbox and motor simulation, and I've heard that planetary gearboxes generally have around 85% efficiency/stage. Which of these would model this better?

Code:

OutputSpeed = inputSpeed * efficiency^numStages / ratio;
OutputTorque = inputTorque * ratio

Code:

OutputSpeed = inputSpeed * efficiency^(numStages/2) / ratio;
OutputTorque = inputTorque * efficiency^(numStages/2) * ratio;

Something else maybe?
