In RL a Ritterkreuz was awarded at first to any commander that sunk 100,000 tons or more, however this amount was relaxed in mid 40 & some were getting the award for only 46,000 tons by late september, (Hitlers U-Boat war by Clay Blair) however tonnage in SH3 is much easier to get so GWX team adjusted the renown to reflect otherwise everyone would recieve an RT after just 1 or 2 patrols, too easy!
