I am glad your opinion means nothing at all to anyone but you. I would be very happy with 5 gpm using 1/2" cpvc pipe and 120 volts at 12.5 amps. That combination would take over the world. But I don't think that is possible either. So I will wait to hear from the company what they think will be best for the market.
Why do you continually focus on the size of the fittings and thererore the maximum flow? Isn't it possible that different models are being worked on to handle anything from a single shower to am entire 3000+ sq.ft. house.
