that's why I was getting annoyed. he was clearly wrong just wouldn't admit it
I am pretty convinced now that he is just a troll on the windup for whatever reason. His complete inability to grasp log graphs, the difference between an average and a minimum, the correct way to compare two data sets to get sound conclusions, geometry and perspective is entirely at odds with his claims on this thread that he is a person who made the 'cream of the crop' to be allowed to serve on a nuclear sub. His actions and his claims lead to four possible conclusions:
1: He is indeed what he says he is and is just a bored troll feigning ignorance looking to get a reaction from people for reasons of his own.
2: He is indeed as inept as he appears to be and was never in fact a serviceman, or at least not one who had to pass a rigorous selection process to obtain one of his postings.
3: He was indeed a serviceman who did come out in the top few percent of his class to get one of his postings, and the entire selection process for US nuclear subs is actually massively deficient.
4: He is just a troll who makes up anything and everything he can just to get a reaction from people.
Given that his 'I'm just asking questions to clarify my understanding' position as an attempted defence of asking questions that have in fact already been answered explicitly is painfully transparent, I'm leaning heavily towards option 4 at this point.
