Yes, but does it match the yaw rate? And what limits it?
yes since yaw rate is dependent upon TR authority. What limits it? I told you it is control power.

Do you mean "rate of pitch change" or "pitch"?
the same thing - to be exact I mean the rate at which the pitch change arm adjusts the pitch of the blade at the feathering hinge.

To make the helicopter move left or right where are the maximum and minimum lift azimuths of the disk? Left and right, or fore and aft?
that depends on your control orbit set up. You need to have the maximum rate of pitch change occur 90 degrees before the desired low or high point of the blade - this is achieved by positioning either the hydraulic jacks of the position of the pitch change horn (usually ahead of the feathering axis) or a combination of both.
