Using exlurker's link, I added up the following tallies for KU recruitment. I took out the duplicate names (hopefully I caught them all), but my total still adds up to 638 despite the article saying that 611 pledged.

Also, the numbers I got for ADPi and SigKap were 3 and 4 higher than reported on irishpipes' thread. I'm not going to recount, but if someone wants to check go ahead!
FWIW:
Kappa Delta: 55
Delta Delta Delta: 55
Kappa Alpha Theta: 57
Pi Beta Phi: 55
Kappa Kappa Gamma: 54
Alpha Gamma Delta: 29
Sigma Kappa: 56
Chi Omega: 52
Sigma Delta Tau: 22
Alpha Delta Pi: 46
Delta Gamma: 55
Gamma Phi Beta: 51
Alpha Chi Omega: 51
ETA: OK, so I did recount (twice) with these changes: Kappa Alpha Theta 54, Kappa Kappa Gamma 56, Alpha Delta Pi 47, Delta Gamma 54, Gamma Phi Beta 54. It was confusing sometimes as girls that evidently had divorced/separated parents were sometimes listed twice, once under each parent.
