Avram
Ive been on these discussions and one of 2 things happen either the people who need to go complain and demand a faster minyan or they quietly vote with their feet and dont come . In many places there are plenty of people for a minyan and its not a problem, but others no so much especially where you have to beg and plead people to come
40-45 Mins will only cut it in a Yeshivish Minyan where people dont have to rush
