Hello,
I recently bought SH3 and I am doing a campaign in which on a single patrol I have destroyed : 1 battleship, 2 passager liners, 1 T2 tanker, 1 Bogue carrier and a C2. The renown I got from this was 1000 points

I find this amount quite small considering that an average patrol of 5 sunken ships gives me on average 500 points
I would like a run down of what are the necessary steps for obtaning maximum renown values and what reduces it during a patrol. I have looked around this forum and saw bit and pieces of information but I think I'm missing a few things. Don't forget that I'm kinda new so please do not omit information thinking that i know it already. I just realised 2 days ago that I have to radio in my patrol report
Thanks for your time.l
