Whatever happened last night (and still no reply from the host) ate a post of mine in here.
I'd suggested that Fleet initiative be used as a potential skill for placing officers in the automated process. Also, political influence should probably play a part if it does not already.
I was thinking, instead of a percentage (or maybe in addition to), political influence is a finite resoure for the officer. If the officer gets promoted due to influence, then his influence gets reduced (he called in favors). The influence builds up over time again with a higher rating meaning a faster recovery.
