Obviously, that only worked on campuses where there was parity. With RFM, that assumption is gone and it is based on chapter performance averages.

A big change with RFM is that they also take into account the % of women who list a chapter first on their bid cards.
So, old system at a school with 2 prefs: If quota is forecasted to be 50, invite numbers would be set so that every chapter would get 100 girls at prefs. 50% return rate? You get to invite 200 girls. 75% return rate? You get to invite 133 girls.
However, you can see that this is predicated on the assumption that all the chapters suddenly equalize and half the PNM's at each chapter pick it. That is obviously NOT the case. If ABC is so awesome that every PNM will list them first, they don't need 100 girls, they only need 50. Letting them have 100 can be disastrous for the weaker chapters.
Another change with RFM is better forecasting. Previously, they used a 3-year or 5-year moving average to calculate return rates. So let's say ABC had 50% in 2009, 60% in 2010, and 70% in 2011. Their forecasting return rate would be 60% in 2012. Well, anyone paying attention would say that is a low assumption, because they are clearly doing better, and it makes sense to assume they'd have at least 70% in 2012. These types of things are now taken into consideration.
