VII skippers, two questions for ya

[Umfuld]

Well I played a year with the stock game with no patches. So those numbrs were something like this by the end:

Tons Per Patrol - 30,000 to 60,000
20,000 or less a rarity.

I try to keep my patrols at three weeks if I can. Seldom two months.
But that don't tell you much because I used a lot of deck gun.

Really just started with the mods and stuff. And while I'm having good tonnage totals with 2 battleships and a carrier, my merchent totals are way down.

Sorry I can't be more help. But I have no extended careers with the updates.
Just thinking with some quick math, I doubt you could do it. Simply not enough eels.
