Hi Mates,
I am trying to figure out the renown for my patrols but it doesn't ads up.
I am playing with 71% realism.
Using this PDF renown table for GWX I found that for large merchant I get 530 points. For Tramp Steamer 60 points & for Passenger /Cargo 90 pointes all total of 15,586 tons.
I calculate: (530 + 60 + 90) * 0.71 = 1128.9
The log file says that I get: 532.10 renown 
Is there a descent calculator for this renown?
Thanks,
Temujin
