In AOD I usually totaled more tonnage than the british empire lost in the whole war.
My current campaign is 1940-03-04 with 5 completed patrols, 28 ships sunk and 197k of tonnage.
This is split in 111k of 24 merchants and 86k of 4 warships (HMS Hood and HMS Ramillies

)
If I stay at that rate I expect 250k of merchant tonnage per year...
