The idea is that each chapter has to release a percentage that should get them to the ideal number of PNM's to have back for that round.
So say there are 100 PNMs, 4 chapters on campus, 3 rounds (open, 1st invitational and pref) and quota is usually about 18, PNMs go to 4 3 2. Chapter total is 100
This is what we know from historicall data (meaning the last three years - just like old release figures):
For the 1st invited the historical return rate is: ABC- 98%. XYZ - 93%, MNO - 80% and TUV - 35%.
For Pref we know that the historical return rate is: ABC - 90%, XYZ - 97%; MNO - 90% and TUV - 15%
Historically - ABC and XYZ always make quota; MNO makes quota or misses by a couple and TUV never makes quota and is usually matches in the single digits. ABC, XYZ and MNO are all at total after bid match and only if they have women that don't accept their bid or they miss quota can they extend any bids. TUV is never at total and is continuously COBing throughout the year.
***This is not a specific campus. Actually, I can think of 4 campuses that I've worked with that would fit into this scenerio! : )***
Old release figures might say that ABC get to invite back 80 women. Do they to invite 80 to their second round when we know they have 98% of women accept? Of course not. Do they need to invite 70? I'd say no to that too.
Even if you go with the 2x quota for pref knowning that quota is about 18 that means they only need 36 invited to pref. If you go backwards using their returns that means that you need to invite 40 to pref to get 36. So they would probably be able to invite 45. This means that they have at least that many at the 1st invitational, but they probably have more like 50 at the round. So to get 50 at their round they would have need to invite 51 PNMs. This means that they had to release 49 PNMs after the open house round or 49%. So ABC starts with 100 releases to 49 releases to 40 and gets quota.
Problem with this scenario is that it still figures in the "old school" 2x quota at your pref events. With RFM you don't get that. We know that ABC always makes quota. We also know that they historically match quota within the first 25 PNM's on their bid lists. This means that they don't really need to have 36 at their events to get quota, they really only need 25. Giving them 28 (25 + a little cushion) and going backwards gets you a completely different set of numbers.
So ABC starts with 100 releases to 43 releases to 31 and usually still gets quota.
This is a 57% release of PNM's for the top chapter after the open house round of events and is not unusual for a chapter with this type of historical data. It also means that 9 women (or HALF a new member class) were release that probably wouldn't have been using the old release figures.
Someone wanted to know if snap bids were higher. I can't say for sure, but I would say that with the campuses I worked with they weren't any higher than normal. I think it's more WHO is snap bidding (meaning they didn't make quota) then how many are being snapped.
It's like 33girl said. PNM's need to think of sorority recruitment the same way they think of college recruitment. You need to apply to a variety of colleges to make sure that you have choices.
