My current build up for last few playthroughs has been a total of 6-8 sub groups and i have gotten around the same results each time in convoy kills.
The current game has me having 7 subs since mid 1940, see pic
29 sub losses, for 254 merchants seems eh...
thats a 700 production point loss (or a little bit more if reinforcements increase in cost based on upgrades, which they should) for germans, for a merchant cost for allies of 2540 production. so around 3.5-4 to 1 kill ratio against AI which seemingly does not pump escorts out effectively.
Edit to add- yes you are correct this isnt a human, and a human will have far better anti sub tactics. we agree. thanks.
