Arc and others
You can. Not a set number but a range. You see in the Yeshivish community and Chassidish community that a specific small date range seems to work. If people used the dates to discuss tachlis and not just blab about stupidity then dating can be and would be short and within a few dates most people would know yes or no. The problem is that there are people who don’t talk tachlis until 4th date or later. Dating is not meant for fun. Its goal oriented. You are basically interviewing the person for the job of spouse. If the right questions are asked and the right topics are discussed it can be wrapped up in an average of 10 dates.
