You have a specific question, there, eric????????

Sure, no two people will do it exactly the same. Aside from the obviouse stuff, zoned or not, there are other considerations.A trunk through a chase to the second floor or feed wall stack up for each second floor regester etc. ACCA Manual D is the best way to do it right whatever style. Perimeter loop, extended plenum, reducing plenum etc.
