220.82 can be used for a yet-to-be built dwelling or service or feeder. 220.83 cannot.

I know that but what I'm trying to say is that you can use 220.83(A) as a loophole for adding additional loads above the calculated load from 220.82.
 
I should have punted on this question, and directed you to an IAEI meeting, often hosted by experienced planners, and retired electricians, perhaps familiar with load calc conventions when less polluted with complexity.

There are good arguments on both sides I'd say

I'd be curious to see some side by side comparisons of the two and a 220.87.

I’ve performed load studies some apartment buildings using fluke instruments. I didn’t perform load studies for an entire meter bank but only for the entire building right at the service entrance. The average demand load for a 60 unit apartment building was like around 350 amps. A 120 unit apartment was like 550 amps.

It's not a loophole. 220.83(A) is a legit way to calculate load for an existing dwelling unit. Just forget that 220.82 exists if you're dealing with an existing dwelling.
