I’ve played multiple games against myself. I can’t remember exactly, but I don’t think the Allies even came close to winning in every game except maybe 1, where Japan was quite incompetent. With players who know the best strategies, it’s incredibly imbalanced.
I have no evidence for this, but I think you first try an Allies 20 IPC bid, see how balanced it is, then adjust it from there. You’ll need to play a lot of games with a lot of different players to get a “good” bid though. Sadly there isn’t a lot of info about Pacific 1940 specifically.
