That has ZERO to do with the number of receptacles that can be supplied by each 15 amp branch circuit. That tells you how many circuits you need.
Each required circuit could have the number of receptacles needed to comply with the rules in 210.52(A)(2) or 10 or even 100 times that number.
The evenly proportioned part only applies the the area supplied by the required branch circuits, and not by the number of receptacles in each area.
Receptacles in dwelling units are not load.
Most of my business is in the industrial field - steel works, paper mills etc. Not exactly DIYers...........!!We do not have 110V either, mostly just DIYers & foreigners calling it that

A good point. They are just convenience.

Just because it is code compliant doesn't make it good design. NEC is NOT a design manual.
Customer wants to cheap out on the electrical even though he's got a multimillion home and have minimally compliant electrical, Advice, Caution, and install per request. Add with warning that in event they are not satisfied the cost will be much more than if done before completion.
Had one the customer insisted on minimally compliant even though strong recommendation otherwise, months later called and complained of tripping. Investigation proved it was simple overload tripping breaker and offered to add some circuits. but they still declined. Found Six larger load countertop appliances on the 2 minimum SABC, metered approaching 30A when tripped, fryers, kettles, grills, and crocks. Don't know, they might have eventually ran multiple extension cords from other areas through doors.

But you just made a leap from calc rules to installation rules that I don’t believe exists.
I do 6 receptacles per circuit and yes I keep them separate

The moment you realize receptacles are for the occupants’ convenience is the moment one is enlightened.
And the correct answer is a wheelbarrow full or a bushel basket or as many as you want.

It’s competing market stupidity.

That is not correct. The VA per outlet is in article 220 and is for calculation purposes.
In the UK and much of the EU as I understand, even for residential construction sites, they do in fact use 110V 50/hz as part of a 'risk assessment scheme' regulations much like our OSHA. It resembles one of our spider boxes, a center tapped 230 : 110/55V transformer. Many or most hand held power tools there were 110V before the cordless revolution. From what I have herd its not uncommon to have one fitted in a workshop also:We do not have 110V either, mostly just DIYers & foreigners calling it that

I share a lot of your reasoning when it comes to this. I usually put all the receptacles on 20 amp circuits, but unless rewiring some old home that doesn't have good heating/cooling systems I usually will end up with more than one bedroom on said 20 amp receptacle circuits. No real set rule on how many and every install will have some variances. Might be simpler to catch a common wall on one circuit but other side of a room could end up coming from a different direction. I generally don't limit to just bedrooms, maybe a living room or similar space might be adjacent to a bedroom and might be common circuit between at least a portion of both rooms.

That was especially common in mobile and manufactured homes back about then. Took me a while to figure it out one time when someone's bath receptacle wasn't working. IIRC on that one the GFCI was at the outside receptacle. Hasn't fooled me since when a receptacle that is in GFCI required location but no apparent GFCI, non continuity between neutral and ground is also a sign that a GFCI receptacle is tripped somewhere upstream.

Isn't that a code violation?
How'd that pass?
But you confirmed my statement DIYers AND foreigners, it's rare for a American professional electrician to call it 110V, there is another thread from a Kiwi doing the same thing for a example. https://forums.mikeholt.com/threads/electrical-panels-built-outside-of-us.2583533/

Actually I say it quite a lot 🫣. I think tho it's usually when having a convo with someone who says it, and I just go along with it and also say it rather than correcting them.
And we do have 110V for
And we do use 110Vac for industrial works. Blue Cement works, BP Grangemouth and many others. But it is usually just the smaller stuff. For example Blue Cement are 11kV for the main drives, and smaller ones are 3.3kV
It wasn't a mobile home but the wiring was sketchy with an FE panel. When we remodeled and did an addition a couple of years later I had the electrician re-do the whole house. Might as well when much of the drywall is off.
That was a while back and asked my inspector about that and he said that it was not against the code back then. Since the 1970's I always installed a separate 20 amp dedicated GFCI receptacle in each bathroom & powder room.
