A couple of other settings to tweak on your 'Capture Planet' strategy:
--Select 'Damage targets until all weapons are gone' under the Damage tab. The theory is that your ships will stop shooting when all the planet's defenses are gone. It usually works for me.
--Under that same tab, set 'Damage Percent per Planet' to something smallish, like between 20 and 50. You don't want to set it too low, in case the planet is heavily defended, so you will keep pounding the planet's defenses while it still has 'em.
