Regarding command time in BA, which seems to be such a critical factor one way or the other for some people, for the 35 years of my experience (and of also being involved with 'postings and promotions') what worked pretty well with a static hull count was:
Look at the compulsory retirement date (CRD) of the most junior Captain (Capt C) on your join date.
With two crew aircraft, this would be the raw date that our new entry at the bottom of the F/O list could expect a command. (y years away)
Assume an attrition rate of leavers before CRD (if any) and loss of licence at 20 per year.
Ball park time to command is the CRD of the Captain who is 20y places higher up the seniority list than Capt C.
