"nice rack"ing up unrealistically huge tonnage

[somedude88]

I keep getting 25,000 to 50,000 GRT per patrol depending on the boat, xii or ix (especially the ix, giving you 4 xtra torps makes all the difference) and I'm not reloading the game after mistakes so that all my sinking attempts are successful.

The thing is, I noticed the uboat aces list on my desk and went to wiki to learn the tonnage records of uboat aces. And I keep blowing those records out of the water by the end of an officers career (I have the option where the career ends after set number of patrols and days) and it feels unrealistic and wrong on some respectful level that some armchair general half their age can outtonnage the greatest the kreigsmarine had to offer.

I know that sh3 intentionally puts out x10 more ships at sea than were historically accurate so that kaleuns don't go weeks without meeting an enemy contact like irl, and that if you do destroy an entire fleets worths of merchant ships, their overall numbers don't actually dwindle, realistically making it harder to find the rest of the surviving merchant fleet.

So I'm asking the community, is there a mod that will decrease my GRT per patrol to more realistic levels? Make it very hard to beat the best aces of the deep?
