Pros and cons to hard cred VS higher adg. Obviously if they are the same value hard cred min is better. I'd take the higher adg over a lower hard number. More days off for pilot group as a whole.

Hard credit means company would no longer build pairings with short days to begin or end a trip. Commuters definitely would be bitten as commutablity would tank from "optimizing".

Whichever solution is chosen will completely change pairing construction.
