The problem with your time period is that the environment radically changes with the 4th. Tikonov used to be hotly contested by the AFFS, but after the 4th, the CCAF was unable to do much about it. Another issue is that the CCAF put a prohibition on raiding Andurien worlds, because the Duchy's units were too effective, and it made it easier to prioritize other fronts. Kalidasa was attacked a few times by sizeable forces, but I would not consider it hotly contested. If you want to talk about grand strategy from a 3rd Succession War POV, you will get a radically different answer than from a 4th, or post 4th.
