Hi!
I think the requirement is Capt and 3 years with Compass before elligibility to transfer to DAL, and then 20 per month, with a yearly cap of "XX" or "X%" per year to DAL. So, it will depend on how much hiring DAL does, and if you can upgrade to capt within 3 years.
Bottom line: Like everything else here on Earth, no one really knows, not even God, as he gave us Free Will.
