Wow, it's been a long time since I flew the 707 as F/E.
The object of fuel loading and fuel burn is two fold. CG & structural.
The fuel is loaded into the wings so as to keep the balance and it is burned the same way.
As the outboard tanks are burned the CG would move forward since the wings are swept.
So the fuel burn runaround chart is using the fuel in such a way as to maintain CG while not stressing the structure.
As CoolP said, you need to keep fuel in the wings to counter the lifting moment.
I have never had the engines quit on a FSX flight and I really don't bother much with the F/E panel.
I suppose if I really took a long flight I might need to do a little cross feeding.
The kind of flying I have been doing in the 707 has just equal mains.
