Fair comment, however common sense must apply. I once had a chief pilot jump up and down yelling and screaming at me because I had increased the power without increasing the RPM first. I cant remember the details, but something like 20"/2400rpm, increased to 24"/2400rpm... Whatever it was, the RPM wasnt supposed to change. When I asked him how I was meant to increase the RPM from 2400 to 2400 he got very agitated.
