The optional load calculation for multifamily almost always comes out significantly less than the standard calculation. I feel like I am missing something. Are we comfortable with the optional 220.84 calculation?

Yep, either method is acceptable.

It is typical that the optional method will give you a smaller service size than the standard method.
