oldsalty, regarding India and third world I think the problem is best addressed by playing with custom income values (rather than a specific rule)
AARHE don’t adjust it as it intends to be a house rule rather than a variant
even then variant map “AARHE 1939” is not that “pure” and gave India 4 IPC hehe
buy some number chips, Imperious can probably tell you where to get that kind of stuff
