If that is true that means DSRF only running more or less 7 years before they left it.
I think that explanation is the best way to describe the number,and it makes sense.
If you go down to the facility to fight omega weapon it looks like there's many buildings in the way you go down.
It looks like there used to be a city but sank in ocean by something.
I think Squall need to find the right frequency to resonating to the rock.
If the frequency is right Ultima Weapon can hear it then go to the source of the frequency and without any clear reason Ultima Weapon fights Squall.
It the same with Omega Weapon, you have to ring the bell first to make Omega Weapon appears.
