I don’t see why testing takes so long. you just play germany italy uk russia and maybe usa for the first three rounds.
you can get 100 trials in one day with optimum strategy based on %s and simple math.
with the current changes UK needs a tank and an infantry, it should still typically lose but at greater losses enabling russia to trade germany territories, which is fair since germany won the seas and italy got africa, europe should be contested - axis should not be able to win in all 3.
Since we are keeping pacific as it is this is easy. Also % of games are won mostly by axis on this forum and in live games in alpha +3.
I am even inclined to say subtract an infatry from one of the italy territories.
