Questions about PD and other

[Sombre]

Yeah the AI is seriously retarded vs PD - when I play against the computer I limit myself to no more than 25 or so PD. 60 PD may be technically inefficient and a bad move, but VS the AI the fact that it comes back every time it wins (which is every time, since the AI has no concept of building up forces before invading) and that it costs no upkeep+supplies,... well against the AI high levels of PD do make sense. Not 100 though, that's just nuts.
