With fear of provoking AZ into a rampage, heres my opinion:
Uniquely devoted $hadchanim, looking for uniquely high earning$, those who Nasi attracts, who see that their efforts dont earn them money unless a Shidduch materializes, might tire of such unique devotion after the newness of the program wears off.
Unique devotion doesnt neccessarily lead to the re$ults these $hadchanim seek. Similarly, unique devotion by top doctors doesnt mean better outcomes for very difficult patients, suffering from hard to cure ailments.
No harm in trying though. Like apricot kernels for cancer, l”a, in Mexico. Sometimes it works.
