How achievable is it to upgrade to captain within 2 years?

given the fluctuation in bases that do the most flying and factoring in a 4 month window after being awarded base of choice, it seems difficult to situate yourself advantageously. Several months ago EWR was considered a base with low opportunity however now its top of the list. I think bidding for home base or base with ease of commute seems like the path of choice.

If upgrade needs to be made by 2 yrs is it fair to say 1000 hours needs to be met within 21 months? That gives 3 months for whatever the process is to transition from sic to captain. Making target monthly flying hours 45-50 hrs.

understood upgrading isn’t required but it would be very nice.
