D”Y: The R”Y directly advising the NASI Project (as well as a bunch of other R”Y) have determined that by and large the majority of the boys stay in EY longer then would be best for their learning. From strictly a shidduch perspective their coming home a few months earlier and thus not artificially putting off their ability to begin dating, would suit each of theirs individual sitatuation.
Btw i have not said anything in terms of aboloshing the freezer. I have simply stated that if boys came back a bit earlier, then instead of them itching to date when the freezer opens they will begin dating when they are ready. (this would likely even enhance their learning). Some would begin the day the freezer opens and some may wait a bit longer. At present -as hello99 pointed out earlier-they essentialy come back ready to date and then they wait.
As for regarding leaving full time learning: It has far more to do with the number of children he has/at what age he has them/what other sources of income etc. Whether he got married at 22.50 or at 23.25 has probably very little to do with how many years he learns in full time kollel after his chassuna.
