What I meant by that is just that after the Seven Years' War, he spends almost all his time in Berlin/Potsdam, except every so often, you see the dot jump southeast to Silesia for a bit, before coming back to Berlin. When I saw the dates on those Silesia appearances, I realized they were in August/September every year, and I went, "Oh, I know why he was there! It was for the military maneuvers I keep hearing took place in the autumn!" I didn't, in case it wasn't clear, mean anything about his specific locations within Silesia. Just that it's showing him there autumn after autumn, and I know why!

Yeah, the later years are :(
