I'm weird; I roll a die. Literally, I keep a 20-sided die handy (I'm a longtime wargamer) and I roll it after each patrol. He gets one number for each patrol, plus one for each 10,000 tons sunk during the career. I use SH3 Commander's realistic career mode and I try to be realistic about approaches and attacks, so I have fairly low scores. I do this for each officer. because often a junior officer might be switched to another boat for his next promotion.
