In all fairness, a LOT of the pilots I speak with ask for more productive trips. You have to consider what that might mean. The company probably said "OK, but NFW are we paying you 5:15 to sit around on those 30-hour layovers". Which probably led to the solution of breaking some of the trips out of rotations as SDP's.
I'm guessing that the genesis.
One important question about how ADG's might affect non SDP trips is whether it will be applied to each day, or the entire rotation. If it's day by day, the company could not afford to have us fly < 5:15 on the first and last days. Adios commutable trips.
So, since I have no language on the ADG's... Imagine a 3 day trip blocked at 4:15/6:15/4:15. Does it pay:
1) 5:15/6:15/5:15, i.e. 16:45
or
2) the greater of block or 5:15 * 3, i.e. 15:45 > 14:45, i.e. 15:45?
