Well in keeping with the rotary nature of this forum, we're certainly going round and round!
Lu, it's true that in some aircraft the swash plate tilts a different direction to the disc, but as Nick says, it's all the same in the end.
Whatever happens, a blade needs to be getting its 'maximum fly down' pitch input about 90 degrees before the desired lowest point on the disc.
If your swash plate tilts down 30 degrees prior to the forward direction of the longitudinal axis, then the pitch change mechanism that follows that swash plate must lead the blade that it controls by about 60 degrees. In the case of the Bell UH-1, the swash plate tilts in the same direction as the disc because pitch commands go to the stab bar, which leads the blades by 90 degrees.
It seems that your basic conception of the rotor 'disc' is a cause of confusion. All smoke screens aside, a rotor blade is just a wing - lift, drag, stalling, angle of attack, relative airflow - all these things are as per any wing.
So flapback, flapping to equality, retreating blade stall and so on can all be fairly easily described in these terms, and it is a misinterpretation to say that some effects are because the blades make up a 'disc' and some are because they must be treated as individual elements.
If you understand the basic concepts of aerodynamic lift and drag, and how airflow behaves over a wing approaching and during the stall, then you won't have any trouble understanding how they apply to a rotary wing.
