I gave you a solution.. a few times. You just seem bent on focusing on the problem.
And there is a VAST world beyond BMG. The system would have us believe otherwise, but it aint so. Like I said, break out of the box, and you’re halfway home. And bli neder, this is the last post I make on the age gap topic. You see the problem, I see the soloution. But I will add this: since whoever put the list of 22 schools together does know who the “under 10%” rate is, THAT should be made public, becuase for whatever reason, their grads ARE getting married. Perhaps not pulling from the BMG pool, but fact is, they are going down the aisle. And hooray for the mechanchim / mechanchos who are at the helm of those ships.. they are doing their job!
And don’t say, “if one wins, its at the expense of another single. If the 20% single rate school knew what the under 10% school knew, THEY WOULD FIND THEIR BASHERT because he is out there. HASHEM GUARRANTEES THAT, so its not me who has a problem with your theory
