We held COB, too. What would happen was that during reading days (at the end of the year between classes and exams), the chapters could give bids to replace anyone who was graduating (or transferring). So let's say Chapter A has 55 girls, but 15 are graduating, they can give 15 bids out during that time. They then pledge in the fall along with the formal rush class. Same thing with chapter B.

Chapter A and B would get quota every time and stay huge. Chapter C would get slightly under quota, but would fill up to ceiling (50) through COB.

Chapters D and E would get only a few girls if any through formal. They'd get a few through COB, but not enough to bring them up to ceiling. Girls who skipped formal rush knew they didn't have to accept bids from D or E; they could wait until the end of the year and get a bid from A, B, or C. Generally speaking (and this is a huge and not always true generalization I realize), the "most desirable" candidates went to A and B; C got their pick of the rest and a few of the best; and D and E got girls who "didn't like the sorority thing" or girls who couldn't get bids elsewhere.
