At 2:00 PM the cascade will simultaneously monitor contacts at four different ages: Scott H. (2.5 hours, high probability), Robert Long (3.75 hours, moderate probability), Jessica Anslow (under 30 minutes, fresh, uncertain probability), and jim (4.75 hours, low probability). This age diversity creates a natural experiment: if engagement occurs, the age at engagement provides data about optimal follow-up timing. If no engagement occurs, the cascade learns that even optimal timing does not guarantee response — validating the pull strategy emphasis on organic discovery over timing optimization.
