not quite because as you upgrade it or what ever it is you do ... the price goes up as well so even if you make trills it will still take quite a few trill to lvl it again
and i think there is a limit to how much you can pay... cause i tried and it said sometihg i cant remember now tho

sorry ars i got made and just attacked top ten ppl
i also tried to clear a system of reavers i destroyed the entire armada and then went to mine only to see that they are still there so i never could mine or anything.... maybe remove the reavers from te test server to make things easier to test?
