It's running @5 years due to the number of pilots that were by passes . Don't forget those that failed will get another chance. It's been written before 3600 pilots now 1800 Capts and 1800 FO's do the maths, next new hire is 3601. New hires do not have an AC to upgrade onto based on the current fleet plan. This year there might be more upgrades on the 330 this year, regardless of AC retirements .
