The ZC cannot have that much money to expand so quickly. Defilers cost 1000 and mission cost money. Unless maybe it is spamming units in a land grab rush (pirates would slow that down). Thinka about it, it has a dozen planets with a few days from the start. :/
I think the AI cheats way too much to resemble 'thinking'. The LUA scripts are once again encrypted so no way to really change the CHEAT behaviour.
