The internal "mean" is to average the monitor data; the second mean is to average the 4 monitor data. Polarization average will be done inside the sweep.

The polarization average can be done in side the sweep of optimization.

As replied early, you can do this either in analysis group with 4 monitors, or in "model" which can control all the monitors. You will need scripting very similar to the analysis group to get the average or sum of the monitor data. Please check the photonics crystal exmaple.
