How so? I can tell PBS to build me a line based of 90 credit hours a month, and it will if I have the seniority to hold that. Doesn't take upper echelon seniority to do that either...just enough to be off the bottom of line holders. Plenty of guys here (YX) crediting >90 hours a month with 17 or more days off. Your crappy lines in a bid packet won't get you that without picking up OT on your very few off days. I've never understood the line bidding is better than PBS argument.
