Q. If I have an option to daven Maariv at an early minyan and count sefira then which is already after an accepted Zeman, or to daven later and count after Rabbenu Ta’am Zeman, that I usually keep on Motzei Shabbos, or should I better daven early because of Zerizim Makdimim?
A. Horav Shlomo Miller’s Shlit’a opinion as quoted by Horav Aharon Shlit’a is that it is better to count early and not wait until Rabbenu Ta’am’s time. which is a stringency.
Rabbi A. Bartfeld as advised by Horav Aharon Miller Shlit’a
