Lu,
I see that you went back and added some additional material to your last post which I just read.
What you are doing is repeating the argument that the R-22 swashplate tilts left at 90 degrees, say, but the pitch horns are not at 90 degrees and therefore precession will cause the blades to be at their high point in the wrong position.
I am trying to get you to see that the blades will wind up at the correct position because of the way the flapping response is speeded up in the R-22 by the use of pitch flap coupling or "delta"
