Not to belabor this but there is another reason our technique of riding works better. Half throttle is a terrible position with regard to battery life. At full throttle the motor is at or near its desired design speed. The back EMF of the motor almost equals the battery voltage and current only is necessary to overcome wind resistance and friction.
At half throttle the motor is only able to run at at half its design speed and during the part of the Pulse Width Modulated cycle during which power is applied to the motor, the motor takes a huge current trying to get to its design speed.
Early in threads about eZips, one rider reported overheating his motor ridding a long distance on a bike path with his wife on an unassisted bike. He attributed it (correctly I think) to running at partial throttle.
