No PBS has everything to do with that... when we had "hard" lines, they built a mix of schedules. The senior guys got pretty good lines, the junior ones not so much. The very next month, with virtually the same parings to be allocated, almost everyones schedule went to ****.

I'm glad to hear that at some companies PBS works well; ideally it should, and can help a lot of people. PBS does not work well everywhere, however.
