So basically:

Railgun I: Practically everyone above 30 in the power ranking, they can start to research Railgun II but that would take them at least three years.

Railgun II: Top 10 powers, can start to develop Railgun III, which would take 2 or 3 yeats.

Railgun III: Top 3 powers, can start to develop Railgun IV.

Railgun IV: Currently being developed, could take two or three years starting from now.
