I'm confused about the meaning of SB levels. At first I thought it would be the number of modules that would increase the function of the base, for example if a mining SB had two modules that increased mining that would raise the level. But, by looking at the equipment on my SB's I see this isn't true.
I have SB's that are heavily armed and defended yet they are still level 0. I notice there is an experience category and that seems to climb with combat...so level is advanced by warfare?
If it is experience, then ships advance levels the same way?
