Sometime sizing apartment load, standard method comes out lower than optional method. However, optional method may come out lower when sizing the meterbanks.
So my question is if we can mix the load calculation method. In my case, sizing apartment using standard method and sizing meterbank using optional method.

An opinion: As long as you base both on raw data (not using standard numbers in optional calculation) I would think it was permissible.
