The math, nor the scenario are correct.
Many articles that I checked on the reference you quote, are either wrong or incomplete, because the articles don't do the complete math, but assume instead a certain scenario, adress some and not all of the relevant forces.
I leave it there, I suggest you consider carefully all forces and the scenario that should be triggered by pilot controls: will he keep pulling collective and not change cyclic ? I doubt that.
