Unnamed, moi? LOL
Kevin, just look everything I have at Six Flags.
In my case i have 2x 20A circuits.
1) Samtag, Magic Chef, Ez-rinse, Silk Lux, Grandma.'Tag, Baby 'Tag, LG, Mini Whirlpool wringer, Thin Twin, World Washer, Ultra mate and Calypso, Mojave and Magic Chef dryer. Note that Samtag and LG have internal heaters.
2) Samsung washer, Skinny Mini impersonator, Marathon washer, Catalyst, Niagara, Hotpoint portable, that round prototype, Mrs. Tag, (gap waiting for Frigidaire Gallery), Samsung Dryer, Marathon Dryer.
I can use all washers at the same time, (NO DRYERS), unless I'm using both samtag and LG on sanitary cycle.
On the other circuit, I can use all washers at the same time but 1) Marathon and Skinny Mini can't spin at the same time if all the other washers are running and 2) if I have Marathon, Samsung and Mrs. Tag dryers running, plus the samsung washer running on sanitary, i can't let the Marathon washer spin and 3) I can't start all dryers exactly at the same time. (I wait at least 30 seconds before starting the next dryer)
All that said, I have an issue much worse than lack of electrical circuits. My water heater. I have only one 50 gal. unit.
During the winter it's impossible to run all washers at the same time. The heater is enough to fill the Marathon, Ultra mate or the Catalyst with hot water, plus one of the front loaders. When I start the third washer, using only hot, the water is already warm (great for light colors). a fourth washer will start filling warm and complete filling with cold (so the water will be lukewarm, more to the cold side, perfect for delicates. a fifth washer is unthinkable because water will be super cold.
During the summer I can use one washer more with hot water and one more with warm. (so 2 loads more at the same time).
Thanks to this limitation, i have to wait until the first washer finishes filling the rinse to then start another washer. this ends up cycling the washers to gradually start using the dryers.
Other thing that helps me a lot is the laundry sink. as I can't have all machines draining at the same time, I already learned a perfect timing to synchronize the washers in a way that they don't drain at the same time. When the Marathon drains (and draw a lot), other washers are filling for the rinse.
I won't consider the 240v machines you have, only the 120v.
Two circuits will me more than enough for you as soon as you wait until a maytag starts agitating before you start the next. this will make the spins always be 2-minute apart from each other. But you can't use the 120v Mieles on sanitary.
You can use the Frigidaire, but ignore most of the others in the same circuit or again, synchronize in a way that it spins when the others are filling for the rinse.
The only thing you really need to focus is "start the next washer when the previous finishes filling".
And again.... Unless you have a wash-in, I really doubt you'll use ALL the washers at the same time. In 3 years here, I used them all only once because i had the roommate's clothes to wash, plus those loads that I rarely have (duvet, blankets because i had a guest, sofa liner, rugs, all at the same time) and you know, I'm kinda OCD sorting clothes.
In your case, AFAIK, you usually have 7 loads per washday (same as I do), eventually 1 or 2 loads more to wash at the same time. Considering the 240v Mieles, plus the first wall, i really doubt you'll have anything left for the 3rd and 4th walls and, if you decide to use the 3rd or 4th walls, the first wall will probably be off.
And... you'll be limited by the water heater recovery time anyway. unless you wash in cold.
