Need help establishing total

[AEPhiSierra]

My campus is considering implementing total when we have never used it before. We are a commuter school with 3 national chapters ranging in size from 11-18 and 3 additional local sorority chapters who don't participate in panhellenic recruitment who also range in size from from about 10-20. Our numbers in recruitment range from year to year with fall classes ranging from 3-7 and spring cob classes of 0-4. Retention has often been an issue do to pledging upperclassman, transfers and drop outs and it this has been reflected in two chapters who have very similar recruitment numbers over a 2-3 year period but having different chapter sizes.

so if anyone here is on a campus with any similar attributes could you please share with me your campus's total/quota/chapter sizes. any other pertinant advice would also be appreciated.

also note that whatever total number is established by the national sorority chapters would not be observed by locals who are competitive on my campus and are 2 of the 3 largest chapters. all the locals preformed better that the nationals in recruitment last year but we feel we have instituted some reforms that should help the nationals a bit.

thanks for the advice!!
