Tzippi: i have no idea what you are talking about. What was meant is some communities are setting it up as date #2/#4 some #1/#4 etc… whatever they feel works for them they will do. some are making different levels 21-24 and 25+ some are not.
Obviously whatever rules each community sets up those are the rules that will be in play.
It’s not just for “shadchanim”. Boys and Girls who have gotten married in the last 5-10 years from each community are the people who will really make this concept work.
