Customers are not stupid for not knowing about duty cycle in the slightest. The scheme you described above is completely incomprehensible. Perhaps if you tried to explain it in more engaging and inclusive ways, "most customers" would not be "stupid". Defining "20% duty cycle" and "bandwidth minutes" and "auto-throttle" in non-technical terms would probably be a good start. Until then, stop being patronising and calling people outside of your area of expertise "stupid". It's not going to win you any arguments.
