I'm not sure exactly why you wanted to emphasize that James, but it is absolutely true.
Most of the people who drop out of rush do it because they were cut from the "top" houses. No one goes through rush wanting the bottom tier chapter. Everyone wants to be in the top houses, that's one of the reasons they are known as the best. So naturally, if everyone wants to be in the top house, that house will not have to worry about making quota... They will get all of their top choice PNM's. They are never going to have to COB. So, the girls who drop out because they were cut from their top choice has almost no chance of getting COBed by that chapter.
The reason that I think we try to talk these poor PNMs into COB is because once they get past the "I have to be in the top house" idea, they are VERY likely to find a sorority that they will be more at home in than they could have thought possible.
I have said before that when I went through, I did not get my top choice house... BUT I decided that being GREEK was the most important thing to me. And in the end, I ended up in a sorority that I have been SO much happier with than I think I would have been had I gotten a bid from XYZ. I LOVE my sorority, and I would not change it for anything.
So, I think we encourage COB because we want these girls to be open-minded and take a look at what they might not have paid any attention to at first glance.
If anyone thinks I am wrong with any of this, please feel free to let me know.
