Our regret with interest is different than what you have all been writing.
I was a swimmer my freshman year and had to miss 2 days of recruitment because of meets (gasp) and I thought I was done for.
The first day I missed (day 1 of recruitment) there were no cuts I or the sororities made, so we simply had an absence with an excuse (I was in a pool, swimming my botty off).
The second day I missed (day 3 of recruitment) I had to cut the sororities I was invited back to down to 3 (you were invited back to at most four, I was invited back to 2). On this day, I regretted with interest to the two sororities on my list, and listed both (meaning I didn't want to cut either).
Our regrets with interest mean you cannot be there, but are still interested in the group. You can simply regret to other groups, but most women don't want to do that.
As a recruitment director, I would feel upset that a group rejected me, even if they still had interest in me. I could see where it might be useful at some schools, but we use the percentages of women returning back from the last year to determine how many each sorority can invite back. (there is a technical term for this, but is escaping me right now
)
I guess I'm on the fence post about it... useful, but I would have hurt feelings
