RFM and New Chapters

[sigmagirl2000]

So, I was curious if anyone out there who knows more about RFM than NUKayDee and myself can enlighten us. I know that the number of cuts a chapter must make each round is dependent upon their return rates historically for each round. However, I am unclear how this works for newly installed chapters going through their first formal recruitment. How are the number of NMs for each round determined for new chapters?

Thanks in advance!
