Thanks for the reply. I did look all through "rush" and didn't find this question addressed - altho maybe I did not make myself totally clear what I was asking. I understand about quota and total. I am wondering in the "intermediate rounds" shall we call them - if there is some formula to determine the number of people who get asked back to each house. At the school I am asking about, there are 12 chapters, and you can return to a total of six, then four, and then finally three.
