The setting of a SRSG is adjusted to maximize the power transfer of a given
arrangement. The peak will occur at a specific phase angle with that set
up. When there are changes in the arrangement of the set up the peak may
occur at a different phase angle so the phase setting of an SRSG would need
to be adjusted to the new peak phase angle. Am I wrong?
I am only stating my understanding as I understand it.
