On the contrary, Health, I think that in many cases, a Cheshbon like DY’s is Glatt and Yashar.
I know a Rav who took a position as Rabbi of a Shul, where he gets little to no pay, for just such a Cheshbon. He has, over the years, effected tremendous growth in areas such as substance abuse and chillul Shabbos d’Oraysa, as well as saving a marriage or two along the way. All of this would have been impossible if he would have been Makpid about talking during Davening.
Was his Cheshbon “Krum”?
