You need to remember to grab new colonies too. There's going to be a point of diminishing returns when sending arcs to existing colonies, so you need to strike that balance of bolster versus new.
I should have PeterKaan's planets by the end of the week, so me and Kai will control our local area pretty solidly when carlwolcott finally falls (which should also be soon). Then we can work on bridging the gap with Vellos, then on to Tom and De-Legro so that we have a pretty large section of the galaxy under BattleMaster control 
I've already got fleets running around all over the place down in your area. Now I just need to do something useful with them.
