How many PMNs "know" before they even start recruitment?

[TriDeltaSallie]

Reading some of the threads about legacies and so on got me to wondering...

At the highly competitive schools, how many women "know" before recruitment that they will receive a bid to their legacy house?

I understand that no one truly knows until they have the bid in hand. And I'm not talking about dirty rushing or saying chapters are promising bids.

But given their connections and perhaps the prominence of their mother/sister/grandmother, what percentage of women do you think start recruitment with almost 100% certainty they will receive a bid to that chapter?

Thanks!
