Excellent job of explaining how the two opposing characteristics interact between the gate and the drain. You've actually taken the explanation one step further than what I've previously heard in relation to class of operation. This also matches exactly what I observed in early testing that was all done in class C prior to stabilizing any oscillations and where the misleading PTC was seen. It is the application of linear bias that causes these devices to operate in the NTC region.
