I just went through my first rush on the
"third side", as an alumna, which made me privy to return numbers and whatnot.
I think that initially, Sorority Life helped to increase numbers at Long Beach State (where there are 7 NPC sororities: Alpha Omicron Pi, Alpha Phi, Delta Delta Delta, Delta Zeta, Delta Gamma, Gamma Phi Beta, and Signa Kappa), where there were over 400 girls who went through Day One of Recruitment.
But the attrition rate of recruitment has really been mutilated by SL. After Day One, there were more than 100 girls who withdrew.
That means that total this year will be much lower than it has been in previous years. Quota is going to be closer to 30, rather than the 42 it was last year.
