Math is not my strongest suite but I doubt we will see to many 850 seat varients being built.
Not only math is not your strongest point but also English, logic and aviation knowledge
The key word lies in the word "typical", which means "in general", "normally". Of course an 850 pax machine wouldn't be built for the long haul routes. They would be high density machines like the 747s within Japan (if we remember). Eighter you fill the tanks or the cabin, that's how goes the saying. Also applicable to other airliners. You cannot have everything. So you choose what is best for you.
Also you have to consider that the present A380 is the first step in an evolution, there will be newer and more advanced models. And as you can see with the 747, the latest models have very few things in common with the earliest machines.
More to come...
