First of all, interesting thread! I have a few remarks though.
You mention nothing about when USA gets into the war? USA1 is 10 infantry and 10 artillery. If you play with OOB rules then USA starts with minor industrial complexes when it’s not at war. This means they can only buy 9 units a turn until they get in the war.
Also i’m not a huge fan of first buying your ground troops in one round and then buying your transports in the next. The reason is i think it’s better to have a few less transports that can move a turn earlier then to have a lot of ground troops stuck on your island waiting for a transport buy the next turn. Even if you’re not planning to unload those transports somewhere meaningful, there is still the psychological factor for the Axis if you move your transports into a position closer to them (for example the famous SZ91). You also mention nothing about the troops you already start with at the beginning of the game. You already have a few ground troops and transports to start the game with!
Also 10 infantry + 10 artillery = 70 ipc, USA starts with 52.
