Sorry, must have missed those. Anyway, at least we agree.
Tourist seems to have difficulty with non-linear equations, which is a shame because in real life there are few linear ones. Obviously if you try to auto with a couple of elephants lashed to the rotor hub, you will reach the top of the L/D curve, i.e. stall. Using linear extrapolation to the absurd to refute an argument is a risky business.
