My understanding is that staying in a higher RPM range for a given load means that the voltage at the motor will be higher and the current lower (since Watts = Volts*Amps), and since higher current (amp) levels = generated heat/inefficiency, this is better.
But I have been wrong many times before.
This week I will do 5 days of "short shift commuting". We'll see what happens.
This motor's fan really blows. In a good way. I can see there a bit of loss at higher revs through the fan.
