Keep in mind. PBS looks at 'pairings' not legs to build a schedule. Junk in = Junk out. If people are not familiar with 'Unstacking' 'credit windows' etc. they have no idea what they're signing up for. PSA is obviously committed to
The 'Junk-in' at present. Until
We have rigs there will be no change, it's the one driver for massive change for the better in pairing construction. PBS solves nothing by itself.
