I still think if you factor in The Pegasus & ENT's TaTV, it displays something of a deep seated guilt that has subconsciously stymied his advancement. They seem to have subtly suggested that he has revealed a self doubt about his worth as an officer, who has prospered in promotion through support from a corrupt 1st captain's influence
I tend to lean towards this. As I said earlier in this very thread, my feeling is that his meteoric rise through the ranks early in his career seen him begin to question, subconsciously, whether he was getting there by merit or nepotism. And as he learned more about what ''really'' happened on
Pegasus, he probably came to dislike, over time, the shadow that his loyalty to Pressman had cast over him and his career. His reaction when Admiral Pressman comes to the Enterprise is one of conflicted emotion, like he's spent a long, long time considering the events aboard Pegasus, and that Pressman's arrival is opening a raw wound for him...
