I'm definitely not a cheerleader, but our PBS doesn't use any kind of globalization (personally, I don't have a big problem with globalization if it's only used to sort pairings within a given preference), the system builds a complete schedule for the most senior pilot, closes it, and then moves on to the number two guy, etc. The system doesn't have the capability to look ahead. Nothing anyone junior to me does has any effect on my schedule -- my schedule is done and closed before the system looks at anyone junior to me.
