Generally speaking, at a colonization the idea is to take average campus size. So, say total is 180, but most groups run around 250 or even 265...then they'll shoot for around, say, 260.
There are bound to be some women who wind up turning down their bids...some who don't actually accept the bid immediately...some who accept the bid and drop after a couple of weeks...with that number, there are always some variations. I believe the women will probably be given a deadline by which to accept or decline a bid. They may even pick up a few more after Friday, to get to average chapter size.
That's just
generally the case...YMMV.
